Benjamin,

	Thanks, I was able to compile the library successfully with the
CVS sources. However, when I try to #include <iostream> in a program, it
segfaults. I've attached some information below. Please let me know what
could be causing this. I don't do much C++ programming and am trying to
get this installed by request of one of our users. Thanks for any help.

Viraj.
