As reported in 10422, gv would not compile on Lion and possibly SL
due to problems building Homebrew's `xaw3d`. That library is a
part of XQuartz now.
* Upgrade `gv` to version 3.7.3.90 from `alpha.gnu.org` because
this release is specifically fixed to support the new `libxawd`.
* Note in the comments to switch back to `ftp.gnu.org` at v3.7.4.
* Change the dep to a Requirement for XQuartz >= 2.7.2.

GNU gv allows to view and navigate through PostScript and PDF documents
on an X display by providing a graphical user interface for the
Ghostscript interpreter.
