implicit declaration of function hypAssignInterrupt - ig_OpenCurrGate_ipi

First time user of parallels,

I am getting this error when running the parallel-config command.

The rpm was giving me libXft.so.1 problems. I installed it with --nodeps options.
Looks like I had libXft.so.2. tried all I can by linking it to libXft.so.1 as mentioned somewhere but it could not find it.
Also tried commenting out the line in the intgate.c where the hypAssignInterrupt is called. Found that it was called in another function as well i.e ig_CloseCurrGate_ipi also. Commented that also and it started giving me something else. So uncommented both and this is the original error as above.

Any help would be appreciated.
