[PD] pointing pd-extended to a different version of libjack? (libjack-0.80.0.so.0: cannot open shared object file)

[rob canning]

hi,
i'm running planetccrma on FC4 an am trying to run pd-extended instead
of the pd that comes with the ccrma package
when i try to run 
cd /home/robcanning/software/pd_extended/bin/ && ./pd -jack
i get:
./pd: error while loading shared libraries: libjack-0.80.0.so.0: cannot
open shared object file: No such file or directory

ldd gives:

cd /home/robcanning/software/pd_extended/bin/ && ldd ./pd
        linux-gate.so.1 =>  (0x00b83000)
        libasound.so.2 => /lib/libasound.so.2 (0x06834000)
        librt.so.1 => /lib/librt.so.1 (0x007b8000)
        libjack-0.80.0.so.0 => not found
        libdl.so.2 => /lib/libdl.so.2 (0x00968000)
        libm.so.6 => /lib/libm.so.6 (0x00941000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x00983000)
        libc.so.6 => /lib/libc.so.6 (0x00816000)
        /lib/ld-linux.so.2 (0x007f8000)

whereas the other pd gives:
ldd /usr/bin/pd
        linux-gate.so.1 =>  (0x00244000)
        libasound.so.2 => /lib/libasound.so.2 (0x06834000)
        librt.so.1 => /lib/librt.so.1 (0x007b8000)
        libjack.so.0 => /usr/lib/libjack.so.0 (0x06516000)
        libdl.so.2 => /lib/libdl.so.2 (0x00968000)
        libm.so.6 => /lib/libm.so.6 (0x00941000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x00983000)
        libc.so.6 => /lib/libc.so.6 (0x00816000)
        /lib/ld-linux.so.2 (0x007f8000)

how do i point the pd-extended to the libjack that i have installed?
or is this the wrong approach?
thanks,
rob
