I guess this is because configure checks all the "normal" places, but has no knowledge of the module specific directories.

To add a bit more detail, it turns out that the configure fails because the native compiler does not support --std=c++03, which is required by gcc48, which is needed to build anything useful.  Yes, this is ridiculous, but that is a real constraint.

I have tried setting GCCBASE=/opt/gnu/gcc in mk.conf to point to a better compiler, but that seems to make no difference.

Is there a way to get pkgsrc to use a compiler other than the native one in /usr/bin?  I have others installed, but cannot figure out how to make pkgsrc see them.

Thanks for advice.

Cheers,
