I just installed cairo-devel and it's working fine now. I didn't get

Thanks for the report. You are not missing anything, I was just a bit
naive and fortunately I'm able to reproduce this issue. Code tries to
dynamically load cairo library using basically this construct:
const char *path = g_module_build_path (NULL, "cairo");
GModule *module = g_module_open (path, 0);
The problem is that g_module_build_path() creates "libcairo.so", which
is available only when -devel package is installed; runtime installs
only "libcairo.so.2", which is not found this way (and I did not expect
that).
I'll have to think & experiment a bit in order to fix this. I'm not
exactly sure how to get dlopenable libcairo.so name - any input from
anyone would be much appreciated :-)
The correct workaround for now as you discovered is to install cairo
devel package, but it is not good general solution, because it would
force end-users of potential lgi-based applications to install it too,
which is ugly.
Would you please mind filling a bug at [1], so that we can stop spamming
lua-l, because it is getting a bit offtopic here.
thanks,
