Ok - sorry - my fault - I didn't read enough carefully :-) - let me know
if you find out what the problem is

Ok - my point was that if you have modified /etc/ld.so.conf, the linker
should be finding libobjc.so without any help, so uncommenting those lines
would change nothing.

Yes - you are right in this case

it shouldn't make any difference, the shared objc library was found
anyway.

Sorry - you're right.
