Correction: I actually meant LD_LIBRARY_PATH above, but LD_PRELOAD would 
work as well. In that case, one would also have to add "/libcairo.so" to 
the path above.

LD_LIBRARY_PATH adds a directory to the list of directories that the 
dynamic linker searches libraries in. LD_PRELOAD is just a brute force 
"load this library" and later when the normal "load libcairo" code runs, 
it will just notice that the library was already loaded.

Cheers,
Uli
