I've looked into this issue. It is harmless and caused by an 
interaction between
AC_TRY_RUN and gcc on leopard.
Gcc generates '.dSYM' directories when linking with debugging enabled. 
These
directories contain detached debugging information (see man dsymutil).
AC_TRY_RUN tries to remove 'conftest.*' using rm, without the -r flag. 
The end result
is an error message during configure and a 'config.dSYM' turd.
AFAIK this not easily fixed without changing the definition of 
AC_TRY_RUN, at least not
without crude hacks.
