To build dynamic loaded you need the extra cost compiler, or really up-to-date
GCC and appropriate 'GNU binutils'. Neither bundled
compiler or older gcc/binutils can build correct position
independant code. It will build static with most gcc's.

You will probably have to explcitly specify pathnames to X11, e.g.
Nick built using GNU gcc-2.6.2 on a 'borrowed' machine like this:

perl Makefile.PL X11=/usr/local/X11R5
make
make tkperl 
tkperl basic_demo 


If you do have the extra cost compiler may also have trouble with some of the
initialized data structures, causing link errors. However it does work 
with the following configuration, compiler and dynamic loading
flags are probably important:

Tk-b8 worked fine for me.  My configuration is:

Since I can't get the commercial version of the compiler, I just installed
the latest gcc (2.7.0) and built with that.  This version of gcc can build
dynamic libraries on HP-UX (if you use binutils-2.5.2).  Earlier versions
of gcc couldn't build PIC code (and hence shared libs) on HP-UX.

Let me know how it goes.
