Alright.

Euh ? Did you do something like "./build-it > build-output.txt 2>&1" ?
The output of ./build-it goes to stdout so if you don't redirect it, it
won't be saved into a file.

Or do "./build-it 2>&1 | tee build-output.txt" if you want to see the
progress on screen as well.

Cfr. my other reply on LTCONFIG_VERSION environment variable.  If you could
set that to the right value and start again (just to be sure this all can
get repeated from a clean start)...
