You misunderstood what Tim asked for. There is the pgplot Fortran and C
library (which you probably have, version 5.2.2). Then there is the PGPLOT
perl module, which is necessary (for historical reasons) for Perl to talk to
the pgplot c & fortran library (this is at version 2.20 now). Then there is
PDL::Graphics::PGPLOT, which makes the whole thing work within PDL, and is part
of the PDL distribution. Tim was asking about the PGPLOT perl module.
