Yep, that seems to be the problem.  In fact, libfcgi.so.0 is not being 
found for any user.

  [carl@dhcppc1 carl]$ ldd 
/usr/local/lib/ruby/site_ruby/1.8/i686-linux/fcgi.so
          libfcgi.so.0 => not found
          libdl.so.2 => /lib/libdl.so.2 (0x4001b000)
          libcrypt.so.1 => /lib/libcrypt.so.1 (0x4001e000)
          libm.so.6 => /lib/libm.so.6 (0x4004a000)
          libc.so.6 => /lib/libc.so.6 (0x4006c000)
          /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)

libfcgi.so.0 is in /usr/local/lib.  I added /usr/local/lib to 
/etc/ld.so.conf, but I'm still seeing the same problem.  I'm assuming 
that it's just because editing the file doesn't update my environment 
automatically.  The thing is, I'm trying to write a shell script that 
will take a default redhat installation and setup apache with ruby-fcgi 
so I would like to know how to get my system to dynamically update my 
changes to /etc/ld.so.conf.

Thanks for all the help.
