hi guys,

when trying to compile one program (Ghemical from 
http://www.uku.fi/~thassine/ghemical/), i got following output from 
configure script

checking GL/glut.h usability... yes
checking GL/glut.h presence... no
configure: WARNING: GL/glut.h: accepted by the compiler, rejected by the 
preprocessor!
configure: WARNING: GL/glut.h: proceeding with the preprocessor's result
configure: WARNING:     ## ------------------------------------ ##
configure: WARNING:     ## Report this to bug-autoconf@gnu.org. ##
configure: WARNING:     ## ------------------------------------ ##
checking for GL/glut.h... no

i recall seeing it before with some other software - but i don't 
understand it. the file indeed is in /usr/pkg/include/GL/glut.h, so what 
's the problem? firstly i thought there could be some problems with 
includes from /usr/X11R6/include/GL, but there's no glut.h there. 
where's the problem?

thanks for any hints. regards,
