Comment(by dominik@…):

 Last year I started toying around with enblend (and the - then new -
 enfuse). I never got the GPU support to work properly, so I usually
 disabled it. My main focus back then was creating a "standalone" version,
 I tried to [http://dev.ultravelours.com/ports/enblend/ document that]. I
 didn't explore that any further, as some things started to fall apart
 (mainly because of non-working universal variants).

 With a few tweaks (the cd command is no longer supported) I was able to
 build a current CVS snapshot with my portfile. I'm attaching a diff for
 the portfile, which should bring the enblend port to version 3.2,
 including enfuse. I'm not a programmer, so maybe someone more savvy with
 TCL and the MacPorts system should have a look at it. I don't have GLUT
 and GLEW installed, so the configure script disables those options
 automatically. There should be some explicit configure.args-append
 directive for that (I didn't try --without-glut or --without-x).

 This doesn't solve the problem with GLUT and GLEW mentioned in this
 ticket, but it should enable people to build a working enblend (and
 enfuse). Did anybody try the GPU-enabled versions and do they really speed
 up blending/fusing?
