The fact that you have to manually load PDL and
that the online help does not work suggests
that something is amiss in the install. I can
suggest a couple of checks:
(1) Try running perldl with the built
version of PDL by running the following
from the PDL source directory:
perl -Mblib perldl
(2) If you have run 'make doctest' then you
should be able to use 'help' and '?' and
other on-line doc features.
(3) You might check what the value of
$PDL::VERSION is after your forced
'use PDL' above.
By default, perldl and pdl2 both 'use PDL'
and support on-line documentation. If you
don't have that then there is a problem
somewhere.
