I think the conditional compilation of the GL screensavers causes troubles 
here. After a default configure I get the rather surprising:

    martijn at martijn:~/src/kde-head/kdeartwork/kscreensaver > bdcompile
    Running /usr/local/bin/unsermake compile...
    kscreensaver/kdesavers/Makefile.am: no rule to create target:
        ../kscreensaver/kdesavers/firesaversetup.moc(../kscreensaver/kdesavers/firesaversetup.o)

I.e. unsermake mistakenly thinks it needs a .moc file for code that should not 
be compiled in at all!

Moving the GL_SAVERS= line outside the if makes it all compile for me. (Didn't 
try linking or running as I have no interest in the screensavers, but 
compilation worked.)

I'm afraid you need someone who knows the stuff about conditional compilation 
though, it seems to be unrelated to the designer version detection. Coolo?
