Actually, I can see what is wrong. I transposed the last two digits - it should 
have been gcc-4.4.3, not 4.3.4

I know I made that mistake in a previous posting, but I thought it was a typo. 
This time I know I it was not. That could explain it.

I'd still like to know how you manage to get both 32 and 64-bit versions of gmp 
and mpfr.
