AIX problems

I think part of the problem with the AIX builds (ld_so_aix complaints)
is due to /bin/which.  It doesn't seem to work.  It's possible it
doesn't work due to my shell (bash), since which is written in csh.

I wrote my own which:

        #!/bin/bash

        for path in `echo $PATH | sed 's%:% %g'` ; do
            if [ -x $path/$1 ]; then
                echo "$path/$1"
                exit 0
            fi
        done
        exit 1

But there are still problems building on the AIX boxes.
I'll try to spend more time on this later.

What is the best time to use the boxes?  They seem to be busy quite
often.  Since they are also starved for memory, it is quite slow to
accomplish work.
