Porters: please make sure you use bsd.port.mk 1.75 or later when
updating ports. That version of the makefile adds all sums. Previous
versions of the makefile will still work for people installing ports.
was defined in bsd.port.mk was checked before bsd.port.mk was included;
this should make ports with optional shared libs build on the alpha,
again. However, chages require the latest bsd.port.mk
version was left at 1.0. Oops. The old tiff (3.3) installed as
libtiff.so.3.3. Install tiff34 as libtiff.so.3.4 but keep the libtiff34
link at version 1.0. confusing but it seems to work correctly.
Update all ports that depend upon tiff so the dependency is on
tiff.3.4.
2) change tiff/Makefile to spit out message saying to use tiff34
remove all tiff files, patches, and pkg data; they're no longer needed
3) install tiff34 as libtiff, tiff.h, and tiffio.h; add symbolic links
so the old names of libtiff34, tiff34.h, and tiffio34.h still work.
4) Change ImageMagick to use -ltiff, not -ltiff34; remove the patch
files and directory as they are no longer needed.
5) Change gimp to use -ltiff, not -ltiff34; remove the patch files and
directory as they are no longer needed.
NOTE: with these changes ImageMagick and gimp require the updated tiff34
port.
