This much I get, it pretty much is the error you get from perl
for an invalid construct.

I don't get these. A couple of things to note: (1)
the number of lines of output is alot but it is just
a stack trace with pretty much a report of a problem
with its location in file/line for each level of the
stack, and (2) reading through I see an error in
.../Devel/REPL/Plugin/Commands.pm line 62.
That is a problem since the latest Perldl2 loads
PDLCommands.pm as the plugin. Commands.pm conflicts and
will give a compile time error. Make sure you are using
the latest Perldl2 from the latest PDL CPAN Developers
release.
Also, try using the find command to see if you have a
duplicate install of the Perldl2.pm profile file which
would also explain the compile error. When you get the
huge backtraces, that usually idicates a compile issue
at the shell internals level.
In future, attaching the startup message with its
information on version and plugins loaded will help
make this more like debugging and less speculation.
Cheers,
Chris
