Thank you, a good point.

Just to let a trace for the posterity, here is what I did:

I now deleted libgmp* from /usr/lib (which I copied from /usr/lib/lib, 
where gmp did intstall, although I configured it with 
--prefix=/usr/lib), then ran:

sudo ldconfig /usr/lib/lib

which updated also the ld cache, and then I defined (in .bash_profile)

LD_LIBRARY_PATH=/usr/lib/lib

After a new login everything could be installed (I installed aws and 
criterion, after which half of Hackage was on my machine ;-) This 
installation point of gmp is a bit odd, but I don't want now to find out 
why the gmp intallation procedure doesn't honor --prefix.

After this I made an AMI (image) of it, which could be used as a start 
point for further installations.

I did not test the installation extesively yet, but by so many 
succefully installed packages, I'm confident that everything is ok. Next 
days I'll play with it.

By the way, I let gmp 5.0.2 there, it looks that HP 2011.04 likes it.
