I think this makes some of the debugging features fail. Some of the
scripts have workarounds that use Agg only if there is no DISPLAY variable
set. If you submit a bug report, I can try to make that usage more
consistent.

I think that's fixed.
This is strange, because all files are installed into /usr in Mandriva (in

I don't know how to get information about a platform's preferred install
paths back to OCRopus so that it can find its files. That's why, right
now, there are hardcoded default install paths, plus an option to override
them via environment variables. If you know how to do this better, please
let me know.
