As you have built your lam for x86-64 (64-bit architecture),
you must
make sure you don't mix it with an incompatible lam version,
or with
objects or libraries built for 32-bit architecture.  Such
mixtures would
produce the sort of hang you mention.

In principle, if you use only the compiler wrappers for your
lam
installation,don't select any separately built 32-bit .o
files, and
don't issue the -m32 option (for gnu compilers; each
compiler has a
different scheme), you should be OK. I may have missed it,
but I didn't
see an indication of whether you are using only a consistent
set of gcc
64-bit compilers.

This is a known issue that we have fixed in the 7.1.3b1 beta
release,  
available here:

Hope this helps,
