[Ubuntu 11] Problem running Penumbra Overture libfltk.so.1.1 not found

[bleki]

Hello everyone.
I succesfully installed p. overture to ubuntu 11.04, but when i try to run penumbra.bin, i receive this error message:

/home/bleki/Penumbra Overture/penumbra.bin: error while loading shared libraries: libfltk.so.1.1: cannot open shared object file: No such file or directory

I am a new linux user. Please, someone help me about this problem. Thanks![/font]

run instead ./penumbra as it's a wrapper around penumbra.bin that sets up the library path to include the "lib" folder. (or use the menus that were added)
