R devel - Sep 2011 - package snow/parallel doesnt make any clusters

I am running R.And  I want to make parallel computations.
When using the snow package under R-2.13.1patched or the parallel package
under R 2.14.0dev, R isn't able to create a cluster. When typing:

cl <- makeCluster(4)

R doesn't respond. It doesn't crash either.

specs:

OS: 32 bit, Windows XP Prof, SP3.
Processor: Intel Core i3 cpu, quad core. 


My colleague works on exactly the same system and operating system, and he
hasn't encountered any problems. What can be the problem?

Best regards,
Maarten Schipper
