Wow - that's amazing, it's not a large/complex program to build.

Ah, that explains it ;) I make the mistake, a couple years ago, of
starting out with that method. It ended up being easier and simpler
to build what I want/need myself from source tarballs (even the GIMP
and its dependencies were straightforward to build).
Maybe it's just me, but I have never had much luck or fondness for
"package management systems" - they either install things into the
wrong place, don't recognize or look for software they didn't install,
etc.

1. Go to http://www.mir.com/DMG/Software/y4mscaler.html and download
the appropriate source tarball. If you're running mjpegtools 1.6.2
then you want y4mscaler-0.6.2, if you're using the cvs version of
mjpegtools then you want y4mscaler-8.1
2. unpack the y4mscaler archive, I use /usr/local/src/ but you can use
whatever is convenient.
3. cd y4mscaler-X.Y
edit the Makefile to comment out the IA32/X86 flags uncomment or
add the flags for the PPC cpu. In y4mscaler-8.1 there are
template/example CFLAGS lines present for both the G4 and G5
based systems:
# ...for the G4 PPC (courtesy of sms):
#CPU_OPT= -mtune=7450 -mcpu=7450 -finline-functions -mdynamic-no-pic
# ...for the G5 PPC (courtesy of sms):
CPU_OPT = -mtune=G5 -mcpu=G5 -ffast-math -finline-functions -mdynamic-no-pic
4. make
'make install' does not exist so you need to copy the manpage and
executable into the desired location.
cp y4mscaler /usr/local/bin/y4mscaler
cp y4mscaler.1 /usr/local/man/man1/y4mscaler.1
Done!
Cheers,
Steven Schultz
