Oops ... failed to 'cc' the list.
(Looks to me that I might not be on the pdl-devel list at this stage, so
please 'cc' me. In the meantime, I'll make yet another attempt to subscribe
to pdl-devel.)

Aaah ... I was guessing that Alien::Proj4->installed *should* be false for
me. (My guesswork is still clearly as crappy as it's always been.)
The problem is that Proj4.pm's @DEFAULT_LIB and @DEFAULT_INC need to include
@{$PDL::Config{PROJ_LIBS}} and (resp.) @{$PDL::Config{PROJ_INC}} - but they
don't.
I don't get bitten by the absence of @{$PDL::Config{PROJ_LIBS}} from
@DEFAULT_LIB because my PROJ_LIBS directory is, as luck would have it, also
in $Config{libpth}.
But @{$PDL::Config{PROJ_INC}} is not found anywhere in the existing
@DEFAULT_INC, and that's what causes check_lib(), and hence installed(), to
return false.
The eval() in check_lib() sets $@ to:
Can't link/include C library 'proj_api.h', 'proj', aborting.
Unfortunately, specifying "use PDL::Config;" in Alien/Proj4.pm is *not* the
appropriate thing to do - as that results in a Config.pm that's a copy of
the previously installed version of that module.
One solution I can see is to have Alien/Proj4.pm parse perld.conf for the
relevant PROJ_LIBS and PROJ_INC settings, for inclusion in @DEFAULT_LIB and
@DEFAULT_INC.
Is there a better way ?
Cheers,
Rob
