Macports installer endless loop

AFAICT, when it works, the installer takes a very long time and loops
around a lot. The real problems is, when it doesn't work, the
installer may never exit and we can't really be sure what's going on
and cannot kill it off. Wouldn't it be just common sense to but in a
loop limit, and have the installer exit with an error if the limit if
reached? Can I see the code for the installer script?

For the life of me I cannot find where this TCL installer is looping
around. Attached is the full log for a successful run. It suggest that
the program will loop approximately 177 times. Doesn't that sound a
little bit crazy?

Anyway we might set a safe loop limit as 200 for exiting the loop.
