In case it isn't evident, I'll point out that you may have some kind of
libstdc++ related incompatibility between icpc and your g++, which looks
like a newer version than those which are fully compatible with icpc.
You might try configuring lam with gcc, g++, and ifort, to see if your
luck changes.
As others mentioned, any -lpthread requirements should be taken care of
automatically.
I'm not expert on the pros and cons of the exports you quote, vs the
specification of compilers in the ./configure command, where it defaults
to the gcc and g++ on your path, so you need specify only
--with-fc=ifort, if you have run the ifortvars.sh script to set the
ifort environment variables.
You do need to set CFLAGS in accordance with your intended usage,
including CFLAGS=-fpic if you want any .so libraries to work. Maybe you
don't care about that; I don't entirely follow what you are trying to
do. If you are trying to make shared libraries, options such as
--without-romio --enable-shared come into play.
