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,
