I changed it a bit (well, first, mozilla is at a different place over here, no
problem with that.)
You nedd to add mozillas bin-dir to LD_LIBRARY path if you use the lsl-directory
structure.
The mozilla lib-dirs need to be first in LD_LIBRARY_PATH if you do
have libraries with the same names as mozillas on your system (it's jpeg for me,
that causing trouble if not using the mozilla one for mozilla).

mp=`expr "$LD_LIBRARY_PATH" : ".*\(/tmp/src/mozilla/lsl-mozilla/lib\).*"`
if [ "$mp" = "" ]
then
  export LD_LIBRARY_PATH=/tmp/src/mozilla/lsl-mozilla/lib:/tmp/src/mozilla/lsl-mozilla/bin:$LD_L
IBRARY_PATH
fi

ld.so.conf is meant to be obsolete anyhow, cause you can do the same by setting
an environment variable (LD_LIBRARY_PATH). And you can see one of the drawbacks
up there (jpeg). How do you manage that mozilla uses it's own libjpeg, but no
other program uses that mozilla lib but the system libjpeg with ld.so.conf ?
