Maybe this is actually a shell script issue, so I'm sorry if this is the wrong place to ask this (reputation suggests maybe it is?!)

I edited the Configure file so that it read:

#! /bin/sh

echo hi there
[download]

Then created an identical file from scratch, in the same directory, trivial.sh. trivial.sh worked completely as expected (printed "hi there" on the command line), but the Configure file did this:
./Configure
./Configure: command not found

sh ./Configure
: command not found2:
: command not found3:
hi there
: command not found5:

I found this which talks (near the bottom) about 'DOS style line breaks'. Could this be the problem? If this is not a suitable place for this question, then I'll ask elsewhere (any suggestions?) but I'd appreciate some (more) monkish wisdom if anyone has any..

cheers
