It looks like it is a known problem:

http://www.xray.mpe.mpg.de/mailing-lists/perldl/2002-12/msg00000.html

It seems to be related to PDL installation options, see INSTALL file. It might be looking for libraries in the wrong place.

Q: I want TriD, but include files are not found.
A: You need to add -I/usr/openwin/include etc. (or whatever is appropr
+iate
on your platform) to the relevant entry in perldl.conf (see above),
i.e. something like
      OPENGL_INC => '-I/usr/openwin/include',
Additionally, you might have to specify name and location of the appro
+priate
library on your platform, e.g.
      OPENGL_LIBS =>
   '-L/usr/openwin/lib -L/usr/X11R6/lib -L/usr/lib/mesa -lGL'.
 ' -lGLU -lXext -lX11',
You may also need to pass some flags to cpp, see the README in the
PDL/Graphics/TriD/OpenGL directory for details.
      OPENGL_DEFINE => '-DGL_GLEXT_LEGACY',
Then, start the build process again as described above
(from the toplevel):
   perl Makefile.PL
etc...
Q: Compilation of TriD complains about undefined functions or somesuch
+.
A: Please see the file Graphics/TriD/OpenGL/README.  If that doesn't h
+elp
   please report this problem to pdl-porters@jach.hawaii.edu, include 
+the
   appropriate platform and GL version information.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
