Description
In spite of the dependency on plplot, p5-pdl fails to configure plplot graphics support. Investigation shows that this option is explicitly disabled by default in ${worksrcpath}/perldl.conf
Default setting in perldl.conf (in spite of the comment, 0 -> disable, 1 -> enable, undef -> auto):
# default settings (let PDL build decide whether to build PLPLOT)
#
WITH_PLPLOT => 0, # Leave it up to PDL to decide
WHERE_PLPLOT_LIBS => undef, # let PDL search for plplot installation
WHERE_PLPLOT_INCLUDE => undef, # let PDL search for plplot installation
Result during configuration
:info:configure User requested no PLplot interface! :info:configure Not building PDL::Graphics::PLplot :info:configure Checking PDL::Graphics::PLplot... :info:configure found_plplot is 0 :info:configure writing dummy Makefile
If perldl.conf is edited to allow auto configuration
# default settings (let PDL build decide whether to build PLPLOT)
#
WITH_PLPLOT => undef, # Leave it up to PDL to decide
WHERE_PLPLOT_LIBS => undef, # let PDL search for plplot installation
WHERE_PLPLOT_INCLUDE => undef, # let PDL search for plplot installation
configuration succeeds as follows
:info:configure Checking PDL::Graphics::PLplot... :info:configure found_plplot is 1 :info:configure Succeeded linking PLplot with -L/opt/local/lib -lplplotd -lX11 :info:configure plsmem function found, in-memory plotting available! :info:configure plsvect function found, vector plotting available! :info:configure c_plgcoloa function found, alpha transparency available! :info:configure c_plseed function found, random numbers available! :info:configure c_plsfont function found, set font available! :info:configure c_plimagefr function found, 2d matrix available! :info:configure c_pllegend function found, Plot legends available! :info:configure Generating a Unix-style Makefile :info:configure Writing Makefile for PDL::Graphics::PLplot
Comments in ${worksrcpath}/Changes indicate that, at least on Windows, plplot integrated support does not build correctly. Workaround is to install PDL first and then install PDL::Graphics::PLplot which, indeed, is packaged as a separate module as well. This isn't well documented so I'm not sure which approach is preferred.
Possible solutions:
- leave perldl.conf as is (plplot disabled), remove the dependency on plplot and reply on a separate p5-pdl-graphics-plplot port (not yet ported) to acheive this support
- patch perldl.conf to enable plplot and keep plplot dependency
- create a variant +plplot that enables plplot when selected

Fixed in r133533. Variant +plplot added to enable build of the PDL::Graphics:PLplot implementation included in the main PDL source. Disabled by default. PDL::Graphics::PGPLOT is the default plotting interface.
It appears that the separate distribution of PDL::Graphics:PLplot is more up-to-date but undiagnosed build problems exist. Committing this fix, as a work around, until these problems can be overcome.
