[Fink-beginners] Execution of ./configure failed, exit code 77

[<bru...@tu...>]

Dear Fink-Beginners List,

Apologies in advance if this has been asked before.  I am new to Fink,
and have just joined this list (today).  I have checked the archives,
but have not seen a problem exactly like this -- though it is certainly
possible that I missed it.

I installed Fink with no problem, but when I try to run "fink
selfupdate" or "fink update-all", I get the output enclosed below.  Note
that it terminates prematurely.  I have no clue what is causing this to
happen, but it looks worrisome.

I am using OS 10.2 (Jaguar).  Might this be causing the problem?

In any case, I would be most grateful for advice, workarounds, etc.

Thanks,
Bruce Boghosian
