[GRASS5] MacOS X compilation errors

[Jeshua Lacock]

So,  I got the ./configure thing working properly, and after issuing 
a "make install", most of it seems to look good initially, but then I 
started to notice a lot of "make" errors.  It complains about 
"/usr/bin/ld: can't locate file for: -lm".

I do not understand what the -lm switch does, and why it can't locate 
the file it needs.

By the way, I am not using CVS because I cannot get PPP working on 
the MacOS X machine....

If I get this part working, I think we will soon have MacOS X binaries!!

Heres a the shell output of a typical module:
