Hi Krzysztof,
are you going to depend on having it installed in usr/lib, or do you know of another solution (via env. vars?), which would not be the cause of setup nightmares?
for testing i installed it into /usr/local/lib, which seems to be a common place. As i'm not very intimate with the linux conventions i'm open for any better solutions (maybe to put the path into ld.so.conf).
best greetings, Thomas
