I am still not clear on what you are saying, and my apologies.
ImageMagick is the only software which does not build and run
correctly on this filesystem. I do not get any permissions errors on
other software, and I've been here about 5 or 6 years now doing this
kind of thing. What precisely is ImageMagick trying to do that it is
not permitted to?
I am going to have to recompile ImageMagick with -g and step through
the source code, aren't I? AIX is so slooooowwwww.... bleh. :-)

What are DFS and GSA? How can I tell if I'm running on them?
The file system I'm installing and running on is a global, cross-
platform file system. To my knowledge, there are no ACL's being
used. And there are no error messages about permissions being
denied.
Yes. This is clear from what '~' expands to:
/g/g0/rcook/...
All cross platform, global filesystems used internally at IBM have
some
form of extended ACLs which render simple file permission tests
useless.
Talk with you administrator about this if you require knowing
exactly what
you're using. When I left IBM (a glorious day) years ago there was
an internal
push to transition to GSA.
And... You're still best served to get this working on a local disk
first,
to ensure all is well, as you'll probably be using xlc as your
compiler.
Better part of valor is to get everything working on a local disk
first,
then try on your global filesystem.
One option may be to open all extended ACLs on a directory, in
other words
all read/write/execute/lock etc. are open. This may allow you to
get a working
system... after you verify all is well on an local disk. Once you
have a working
system on an global filesystem, you can play with closing one set
of ACL perms
at a time, to ensure ImageMagick works with every ACL change.
Again, refer to
your administrator for assistance.
Once you know what you're really using (DFS/GSA/GPFS/GFS) you can
change
your ACLs accordingly.
