Re: [pure-lang-users] 64-bit build-problems

Eddie and Albert,

Thanks to you both.
Ubuntus are bad, refusing to update their very old version of LLVM, 
despite having had a request for it for the last six months or more.

I have just found a .deb package of LLVM2.2-7 at: 
http://ubuntu.cica.es/debian/pool/main/l/llvm/
which might turn out to be the easiest way to go. 
I am just going to try it and report here.
