i would recommend to install libquicktime from the sources :

http://prdownloads.sourceforge.net/libquicktime/libquicktime-0.9.1.tar.gz

( ./configure; make; make install )

then to add the line : /usr/local/lib in /etc/ld.so.conf

and finally to run 'ldconfig -v' so that it could find the new library.

cheers, sevy
