In the RPMs from ftp.mozilla.org for RH62/0.9.3/i386, the shellscript /usr/bin/mozilla uses the program "readlink" to find the JVM plugin. /usr/bin/readlink is part of the 'tetex' RPM, but the mozilla RPMs don't require tetex to be installed. Perhaps the dependancy on readlink should be removed, instead of requiring tetex for only this (I have no need of tetex, so it's not normally there).
Fixed in the 0.9.3-1 rpms. That was an old version of the script - I'm not sure how it snuck in there.
