I have the same problem. I just compiled under Fedora 13 64bit following the
"svnAlongStable" method, the kio_digikamalbums.so is located
in /usr/local/lib64/kde4/ so I've changed the path in the script accordingly
- export
LD_LIBRARY_PATH="$DIGIKAMDEST/lib64/kde4:$DIGIKAMDEST/lib64:$DIGIKAMDEST/lib:$LD_LIBRARY_PATH"
- same with LDPATH. But I'm still getting the same error - digikam(16815):
couldn't create slave: "Není možné vytvořit io-slave: klauncher hlásí: Chyba
při nahrávání 'kio_digikamdates'.

Also compiling this on Fedora is harder than I'd thought. libkexiv2 had some
building issues, which I managed to resolve. DigiKam also had some build &&
linker issues. I don't know why, but cmake picked the right libkexiv2 and
libkdcraw libs in /usr/local, but during make, it was using the distribution
ones. Same with include dirs. I don't know cmake too well, so after trying
to set few parameters I ended up moving the system include files to some
other place. Then I just run make again and it picked up the right includes.
Same with libs. Maybe this is 64bit system related...I don't know. What may
be the issue here?

Later I might also send the steps needed to build digiKam on Fedora,
including needed packages, if it would be wanted for the howto.
