Hi Miklos, Eike & Jose for your help so far. I have taken your suggestions on board but still the gstreamer problem persists. Firstly, Jose's excellent idea of a pre-install script. This ran through the yum component but I got an error ./pre-install.sh: line 58: [: ==: unary operator expected mkdir: missing operand Try 'mkdir --help' for more information. pre-install.sh <http://nabble.documentfoundation.org/file/n4034740/pre-install.sh> I have attached pre-install.sh just in case I downloaded incorrectly. Line 58 reads: if [ $clonedir == "" ]; then Anyway, I figured that should have installed all dependencies so I ran the "git clone..." manually. I dropped down in to the libo directory and tried ./autogen.sh. Unfortunately I got the same errors with libgstreamer. So now I am moving away from LO territory and into Fedora land. I posted a question on the fedora forum but no response. Yet. Any ideas whether there is a special repo for libgstreamer? I found an rpm which will install this: http://rpmfind.net//linux/RPM/fedora/18/i386/g/gstreamer-0.10.36-2.fc18.i686.html <http://rpmfind.net//linux/RPM/fedora/18/i386/g/gstreamer-0.10.36-2.fc18.i686.html> Does this look like it would do the trick? I am a bit nervous about installing things which did not come from the obvious (yum) channel.
