[geos-devel] Compiling with Ruby support

[Michael Moore]

Hello,

I'm trying to compile GEOS with Ruby support. I'm using the latest
source code from git, and I'm on Debian.

I'm a little rusty on my g++ flags and can't figure out why g++ can't
find libruby. Could someone point me in the right direction?
