Hi Michael,
ParaTools, Inc. has ported SAGE successfully to AIX! We had to
rebuild the library and debug it further
but now I can say:

The last error was resolved by printing the type of the object that
was of type pari.gen. When we
rebuilt that library by hand and the dependencies, it worked. I should
also add (for the list) that we had to
build clisp and gap in 32 bits and change gap.py to use a fixed big
number for the file descriptors as the max
fileno from getrusage was not working properly in AIX. This change
fixed pexpect.
Thanks a lot for your help! I look forward to discussing these issues
and help with
documenting this at the SD 11 with you.
