[R-pkg-devel] Problem loading package on Windoze --- update.

[Rolf Turner]

I've just heard from another member of the client group and he cannot 
reproduce the problem.  I.e. he can install both the source package and 
the binary that I sent out, without error.

So the problem seems to be in the system used by that first member of 
the client group who contacted me.

Sorry for the noise.

cheers,

Rolf
