Unix/X-Windows Question: I'm attempting to install Hydrogen on my OSX Mac (X11 installed), and when I run "./configure", it throws crazy errors: "checking for g++... no, checking for c++... no, checking for gpp... no, checking for aCC... no, checking for CC... no, checking for cxx... no, checking for cc++... no, checking for cl... no, checking for FCC... no, checking for KCC... no, checking for RCC... no, checking for xlC_r... no, checking for xlC... no." I've had these problems before, in another context, but I can't remember how to install the modules. Hope me! Bonus points for a thorough explanation of the "why," not just "how."
