Log message:
Turn MESA_REQD back into a public variable, and make it take a list of
values that MesaLib/buildlink3.mk converts into a single _MESA_REQD that
is the highest version required.  If including the Mesa/buildlink3.mk
file, then require the same version of Mesa as required by glut.

Log message:
Require at least the same versions of MesaLib and glu to build.

Log message:
version.mk no longer defines MESA_VERSION.  Put the version number of the
required package in its place.  Thanks to Jan Schaumann for diagnosing the
problem.

Log message:
Append to BUILDLINK_DEPENDS.<pkg> instead of setting a default value.  In
the normal case when BUILDLINK_DEPENDS.<pkg> isn't specified, it receives
a value only once due to the multiple inclusion protection in the
bulldlink3.mk files.  In the case where a package includes several
buildlink3.mk files that each want a slightly different version of another
dependency, having BUILDLINK_DEPENDS.<pkg> be a list allows for the
strictest <pkg> dependency to be matched.

Log message:
Mesa-6.0 packages now use LIBTOOL and finally build
