Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.

Log message:
Drop superfluous PKG_DESTDIR_SUPPORT, "user-destdir" is default these days.

Log message:
Remove xextproto/buildlink3.mk in most cases where it occurs with
libXext/buildlink3.mk, now that it is included there.
Leave the places where its API version is set or variables from it
are used directly (about 3 packages).

Log message:

Log message:
Don't hack a seperate game manual suffix/directory in behind
xmkmf's back. Makes this install cleanly on Solaris.

Log message:
back out last change - broke on NetBSD after all, test build was in wrong
directory.

Log message:
On Solaris, the (source) man page would be installed to man1/xsnow.6,
which is not only inconsistent with the man page directory tree, but
also with the PLIST. Fixed by this change. Installing on NetBSD is not
affected.

Log message:
Update MASTER_SITES and HOMEPAGE to new location.
