gal2 lib check wrong (from gnumeric2)

[Mike Harding]

gnumeric2 Makefile checks for gal2.0.0, gal2.0 is what's installed.

...
===>  Installing for gal2-1.99.2
===>  gal2-1.99.2 is already installed - perhaps an older version?
      If so, you may wish to ``make deinstall'' and install
      this port again by ``make reinstall'' to upgrade it properly.
      If you really wish to overwrite the old port of gal2-1.99.2
      without deleting it first, set the variable "FORCE_PKG_REGISTER"
      in your environment or the "make install" command line.
