Finally got some time to mess with this thing...  Since this isn't the 
standard configure script most packages use, I'm skipping the packaging 
section for now and going straight to compiling.
Natively compiling, so far I've tried configure with no options, and 
I've tried specifying the lib and include folders explicitly.  If all 
else fails, I might get to learn a bit about cross compiling.(I've 
read/heard that it can be quite painful the first time)  =)

libstdc++.so.5 exists as a link in /opt/lib/
lrwxrwxrwx  1 root root      18 Jun  2 07:50 /opt/lib/libstdc++.so -> 
libstdc++.so.5.0.7
lrwxrwxrwx  1 root root      18 Jun  2 07:50 /opt/lib/libstdc++.so.5 -> 
libstdc++.so.5.0.7
-rw-r--r--  1 root root 4569715 May 25 12:18 /opt/lib/libstdc++.so.5.0.7

Any hints for the output below would be helpful.

-bash-2.05b$ ./configure compile:-I/opt/include link:-L/opt/lib
Box build environment setup.

Checking environment...
Compiler 1: yes
Compiler 2:./envtest: error while loading shared libraries: 
libstdc++.so.5: cannot open shared object file: No such file or directory
 no

================

The C++ compiler fails basic C++ tests. It is impossible to compile and 
deploy this
software on this platform.

Some less common platforms do not have a working C++ implementation, 
especially
regarding modern language features such as exceptions. A basic test 
failed. It is
unlikely that you will be able to use this software without fixing the 
compiler.

You could try a later version of the compiler, if available.

================


Aborting configuration, cannot build in this environment.
-bash-2.05b$


Thanks!
