Looks like gl support is designed for windoze ... 
gl/gl.h should be GL/gl.h ...

I am not sure about "redeclation of ColorMap256", but changing gl/gl.h to
GL/gl.h does not fix that problem.

Workaround: setting USE -opengl works.

I was able to re-produce.

Adding "-opengl" is a working workaround also.

I don't think we should even support USE="opengl" for this ebuild.  The code
appears to use some SGI-specific opengl functions from what I can determine.  

There *is* a library available (http://www.thp.uni-duisburg.de/Ygl/ReadMe.html)
which provides these on an X11 platform.

It also doesn't appear that the library is expecting GL and X11 to be enabled at
the same time.  See function dev2gif.c::DumpScreen2Gif, which redefines
ColorMap256 if you enable both.

It'd probably be less trouble to drop USE="opengl".
