was really simple, but I did not think about it.

Joe,
Excellent! this worked out perfectly...
thank you so much for your help.
Perhaps these shapefiles should be published somewhere, since it really is useful to have.
I wasnt able to find it anywhere on the web.
anyway, problem solved; you saved my day.
thanks again,
P.R.

Ah, sorry I misunderstood. 
You can get them by using GMT's gshhs tool (or just using pscoast with the right options) to dump out the political borders in GMT format and then convert them to a shapefile using ogr2org (or whichever tool you find easiest... Personally I use the python wrappers around ogr for more control.)
To save you a bit of trouble, I zipped political boundary shapefiles (from GSHHS version 2.0, so they'll coincide perfectly with the GSHHS coastline data) and put them here: http://www.geology.wisc.edu/~jkington/borders.zip
There's probably a way to do it using basemap, as well, but I don't know it off the top of my head.
Hope that helps,

If you just need the GSHHS data in shapefile format, it's available on the NOAA GSHHS website.
If you prefer a direct link [96MB zip file]:
http://www.ngdc.noaa.gov/mgg/shorelines/data/gshhs/version2.0/shapefiles/gshhs_shp_2.0.zip

The regular GSHHS dataset doesnt appear to include political boundaries, however the GSHHS dataset used by matplotlib/basemap does include country/border data. I'd like to extract matplotlib/basemap GSHHS country data & convert it to shapefile format.
specifically, the following files that are included with matplotlib/basemap:
countries_c.dat
countries_f.dat
countries_h.dat
countries_i.dat
countries_l.dat
countriesmeta_c.dat 
countriesmeta_f.dat
countriesmeta_h.dat
countriesmeta_i.dat
countriesmeta_l.dat
how can I convert these files to shapefile format, or where can I get shapefiles that already include this data & that are based on the GSHHS coastline data?
please help,
thanks,

that almost fixes it. I can now plot and re draw during the execution of my
script. However I cannot interact with the plots. i.e. I can't zoom in on
an area. when the script gets to the point where pyp.show() is called then
I'm able to do this. I'm thinking there may be no way round this?
or is there some way to run matplot lib plot in a different thread?

I made binaries (on Mac OS X 10.5) using my instructions:
<http://www.astro.washington.edu/users/rowen/BuildingMatplotlibForMac.htm
l>
They are available from here, for now:
<http://www.astro.washington.edu/users/rowen/python/>
please test them. If they work then I hope the matplotlib folks will 
consider serving them as official "for 3rd-party Python" binaries
(as opposed to the current ones they are serving, which are for Apple's 
Python).

I finally solved it my self, after half a day of headbanging. This did the
trick for me, it is really good since it uses the values of the lower x
axis, so you do not have to go in fiddle with ticklabels etc, it also
changes values when you pan/zoom etc.
fig = pl.figure(1,figsize=(10.5,8))
fig.clf()
ax_kms = fig.add_subplot(111)
ax_kms.step(velocity, spect)
ax_hz = ax_kms.twiny()
x_1, x_2 = ax_kms.get_xlim()
ax_hz.set_xlim(calc_frequency(x_1,data.restfreq/1e9),
calc_frequency(x_2,data.restfreq/1e9))
Great!

hi, 
thanks for the response.
I already have & know how to use the GSHHS coastline data; what I need is political boundaries (country borders) data that will coincide with the GSHHS coastline data. In other words, I can't simply use any political boundaries shapefile, since the coastlines will not line up with the various resolutions of the GSHHS coastline data. I hope this makes it a little more clear...
