[Koha] Zoom install error

Hi all, I am trying to install koha-2.2.9 on a Fedora Core 6 box but I get an error saying that I am missing the Zoom module. The corrective action is to install it via the perl -MCPAN -e 'install "ZOOM"' command. However this leads to an error: /usr/bin/ld cannot find -lexslt Collect2: ld returned 1 exit status Make: *** [blib/arch/auto/Net/Z3950/ZOOM/ZOOM.so] Error 1 /usr/bin/make --NOT OK Running make test Can't test without successful make Running make install Make had returned bad status, install seems impossible I have also tried to download the tar and install it manually to no avail. Can anyone tell me what I am missing. Thanks in advance, Dave
