please use 4.0.1 before messing with the cvs.
if you are having trouble to compile the cvs code,
that you should not use development software.

ouch. intel 10.1.008 is known to be a _very_ broken compiler.
please update to a recent patchlevel. check out the mailing
list archives. this topic has been discussed several times
in the recent weeks.

hmmmm... 
so you want to use the 32-bit version of the compiler (ia-32) 
on a 64-bit install.

...and you don't have the 32-bit development libraries
installed. how should this work? this is not the fault
of quantum espresso but a faulty installation. fix your
installation and try again.

cheers,
