pkg_create fails for math/pari

[Iain Morgan <Iain.Morgan%nasa.gov@localhost>]

Hello,

While trying to install math/pari, pkg_create fails with the following
message:

=> Automatic manual page handling
pkg_create: can't stat 
`/u/imorgan/work/math/pari/work/.destdir/u/imorgan/pkg/lib/libpari-gmp.la'
=> Creating binary package 
/u/imorgan/work/math/pari/work/.packages/pari-2.3.5nb13.tgz
pkg_create: can't stat 
`/u/imorgan/work/math/pari/work/.destdir/u/imorgan/pkg/lib/libpari-gmp.la'
pkg_create: lstat failed for file lib/libpari-gmp.la: No such file or directory
*** Error code 2

It turns out that while gmp is enabled as a default option for math/pari,
it is not actually listed as a dependency. Thus, if devel/gmp is not
already installed, libpari-gmp.la will not be created and pkg_create will
fail.
