Both appear to have support:

[neteler at north ~]$ rpm -qil lib64cairo2-1.9.6-3mdv2010.1 | grep 'so.'
/usr/lib64/libcairo-script-interpreter.so.2
/usr/lib64/libcairo-script-interpreter.so.2.10906.0
/usr/lib64/libcairo.so.2
/usr/lib64/libcairo.so.2.10906.0

[neteler at north ~]$ ldd /usr/lib64/libcairo.so.2 | grep 'free\|fontc'
        libfontconfig.so.1 => /usr/lib64/libfontconfig.so.1 (0x00007f3be8b80000)
        libfreetype.so.6 => /usr/lib64/libfreetype.so.6 (0x00007f3be88f8000)

[neteler at north ~]$ rpm -qil libcairo2-1.9.6-3mdv2010.1 | grep 'so.'
/usr/lib/libcairo-script-interpreter.so.2
/usr/lib/libcairo-script-interpreter.so.2.10906.0
/usr/lib/libcairo.so.2
/usr/lib/libcairo.so.2.10906.0

[neteler at north ~]$ ldd /usr/lib/libcairo.so.2 | grep 'free\|fontc'
        libfontconfig.so.1 => /usr/lib/libfontconfig.so.1 (0xf75e7000)
        libfreetype.so.6 => /usr/lib/libfreetype.so.6 (0xf7563000)

I have opened a bug report in the Mandriva tracker.

Yes, this works as workaround, thanks.
