Thanks for your advice Chris.
I downloaded the latest 2.4.4_08 source and proceeded per your
directions. I commented out the PLplot building switch in perldl.conf,
but then I got the following test failure for HDF
t/hdf_sd....................ok 28/32PDL: Dimensions must be positive
Caught at file t/hdf_sd.t, line 306, pkg main
# Looks like you planned 32 tests but ran 31.
# Looks like your test exited with 2 just after 31.
t/hdf_sd....................dubious
Test returned status 2 (wstat 512, 0x200)
DIED. FAILED test 32
Failed 1/32 tests, 96.88% okay
So, I turned off HDF as well. Interestingly, while HDF was not build,
I still got the above test error. Anyway, then I proceeded to make and
make install. It all seemed to work. Then I went into perldl and got
the following --

Any further suggestions?
By the way, I did follow the instructions on PLplot website to build
it on my computer, but, as I noted in an earlier email, when building
PLplot, it seems to look for the existense of PDL::Graphics::PLplot
which is really confusing. I thought it would be the other way
around... the P::G::P would depend on PLplot, not the other way
around.
Puneet.
