That probably means /usr/local/csw/lib isn't in your library search
path (check with "ldd a.out"). You have three options:

1. Do "env LD_LIBRARY_PATH=/usr/local/csw/lib:$LD_LIBRARY_PATH
./a.out". Try this first -- if it solves your problem, you know that
the library path was indeed the issue.

2. Add /usr/local/csw/lib to the dynamic linker's config file,
typically /etc/ld.so.conf .
3. Give additional arguments to the linker to modify the runtime
search path of the executable. This varies considerably (options like
-R or -rpath), check your linker's man page.
