[J B]

/usr/local/bin/bash
cd /usr/ports/editors/libreoffice/work/libreoffice-core-3.5.2.2
source ./Env.Host.sh
cd vcl
gmake clean # optional
gmake -r

when the problem is isolated and fixed exit and re-run 'make' from the top-level
gmake[1]: *** [build] Error 1
gmake[1]: Leaving directory
`/usr/ports/editors/libreoffice/work/libreoffice-core-3.5.2.2'
gmake: *** [source-env-and-recurse] Error 2

Stop in /usr/ports/editors/libreoffice.

OK.
I did as instructed above (up to 'gmake -r', and I got a clean compile.

It seems to be a clean compile. So, what is the problem ?
If I do it all  ('make') from the top level (as I have done it many
times), it fails as documented here.
What next ?
