Yup. Sorry about that... But that didn't work either.

OK.

Well - I didn't write it ;)

Sounds reasonable indeed...

Ah... I see.

Yes - that's how it looked to me to (hence the subject :)

Hm. OK - this posting is getting long-winded anyway... :)

<sigh>

After poring over this dump I think I suspect something (which *might*
be construed as a weakness in the make-control ;)... It guesses the
wrong location for my installation... The /store/lib/python1.5 stuff
isn't mine... I have used an alias for python to point to my own
installation.

But even so, I'm to tired to figure out the connections...
