I should have added my congratulations and gratitude for taking 2.4.9 to a
point that it builds and installs beautifully, without any heartburn. Perhaps
because most of the dependencies got installed when I installed 2.4.6 via
MacPorts.
I am doing a lot of stuff using R, so am curious to try out PDL::Stats. For
now, I am using R compiled inside Postgres using PL/R... what a wonderful
experience to get my data out of Postgres and analyze it right within the
database.
Wrt PDL::Stats, my guess is the test failure has nothing to do with it being on
a Mac/10.7. Perl 5.14.1 should be Perl 5.14.1 no matter what platform, no?
