I don't think it is a big problem, but gtk-perl-0.7008-r10 does most of its compilation (gcc calls, etc.) during src_install instead of src_compile. As I really don't know anything about the perl make process, I'm not sure if it is a normal behavior for perl modules or not. Sorry in case it's not a bug. Reproducible: Always Steps to Reproduce:
In this case, it isn't a bug. Those calls are for the configure to determine what needs to be built for your box (gtk-perl attempts to guess what you have available and what you can support).
