problema con pSX y libreria libgtkglext

queria installar el emulador pSX para jugar play en linux en debian lenny, cuando me encontre con la siguiente sorpresa

pint0@debian:~/pSX$ ./pSX
./pSX: error while loading shared libraries: libgtkglext-x11-1.0.so.0: cannot open shared object file: No such file or directory

abviamente me falta ese archivo por lo que bastaba con hacer un apt-get install libgtkglext

y se vera algo asi y se elige el que dice "Shared libraries"

debian:/home/pint0/pSX# apt-get install libgtkglext
