rpmbuild screws up install path with mythtv

I have been trying to build a rpm of mythtv (with sources from Øystein <http://folk.uio.no/oeysteio/ > and a additional patch to make it compile) for my 64 bit box and am getting strange errors. I can compile it just fine using normal ./configure qmake make procedures, but when using rpmbuild after setting prefix to /usr with configure, it tries to install in the prefix ../../../../../../ which is not very helpful. I have also manually done the same things as rpmbuild is suppose to do after letting it prepare the sources and get the /usr prefix as it is supposed to have. Could anyone give me a hint? -- Guðlaugur Jóhannesson http://www.hi.is/~gudlaugu Tel: 840-8405
