I re-built the package, fixed the path to the binary and tested on 64-bit myself. Seems to work.
Anyone who wants to try out the new package, use slapt-get or gslapt to remove your current package, and install the new one.
NOTE: Package name did not change, so it will not show up as an update.
NOTE2: Package must be installed with gslapt or slapt-get with the untested repository enabled. Otherwise, it will not find the Mozilla-nss package it needs.
