I wasn't sure how to get the SVN version, so I am trying to install
PLIB 1.8.5, but ./configure is failing.
Here is the last bit of the ./configure output(everything before it is yes):
checking for pthread_create in -lpthread... no
checking for glNewList in -lGL... no
checking for glNewList in -lMesaGL... no
configure: error: could not find working GL library
