Are you following the directions here?

PDL TriD requires FreeGLUT and not GLUT libraries
except for Mac OS X which has a non-standard GLUT
with the needed extensions.

You'll need to have versions and build log errors
for everything: modules, compilers, ....
If you open a bug on PDL tracker at sf.net
you can conveniently attach the needed information.
Also, are you using 32bit or 64bit Ubuntu.

You'll need to remove the files by hand.  Most times
you can just force install and overwrite the existing
version.
