Weeks?

If you're building from source, FOX doesn't depend on any particular 
version of the standard C++ library.

If you're installing it from an RPM it would presumably have a 
dependency on whatever version of libstdc++ it was built against on the 
RPM packager's machine. For example, if the packager built a FOX RPM on 
Red Hat Linux 8.0 it probably wouldn't work on earlier versions of Red 
Hat Linux, or for other Linux distributions that happen to use RPMs 
(such as Mandrake).

Since you're talking about dependencies on particular versions of 
libstdc++, am I correct to assume that you're trying to install an RPM 
that you found somewhere, and that rpm is complaining about that dependency?

I usually keep up-to-date RPMs for Red Hat Linux 8.0 here:

	http://sourceforge.net/project/showfiles.php?group_id=3372

but some other sources for RPMs/DEBs can be found here:

	http://www.fifthplanet.net/cgi-bin/wiki.pl?Download

I didn't build any of those other RPMs or DEBs so I can't comment on 
their reliability, etc.

To sidestep the issue of binary incompatibilities for this RPM or that 
RPM, I would just go straight to the source (literally). Download the 
latest source tarballs for fox-1.0, FXRuby-1.0 and FXScintilla-1.x.

Start by getting a working FOX installation before moving on to 
FXScintilla (which would be step 2) or FXRuby (step 3). For most 
*recent* Linux distributions this usually just involves:

	tar xzf fox-1.0.29.tar.gz
	cd fox-1.0.29
	./configure --with-opengl=opengl
	make
	make install

and then running some of the test programs (in the fox-1.0.29/tests 
subdirectory) to make sure things are working. Do not proceed past this 
step until you're satisfied that things are OK.

Once that's working, move on to the FXScintilla build. Again, if you 
have a good FOX installation this should just involve the usual:

	tar xzf fxscintilla-1.49.tar.gz
	cd fxscintilla-1.49
	./configure
	make
	make install

I am not the FXScintilla developer/maintainer, but I think Gilles still 
has a little test program somewhere in there that you can run to see if 
it's working.

The last step is to build FXRuby. For most cases (under Linux) this 
should involve:

	tar xzf FXRuby-1.0.17.tar.gz
	cd FXRuby-1.0.17
	ruby install.rb config -- \
	    --with-fxscintilla-include=/usr/local/include/fxscintilla \
	    --with-fxscintilla-lib=/usr/local/lib
	ruby install.rb setup
	ruby install.rb install

If you leave out the '--with-fxscintilla-xxx' options it will *not* 
build FXScintilla support into FXRuby and as a result FreeRIDE will not 
work. I will probably change this for the next FXRuby release, so that 
it snoops around a little to try to automatically detect the presence of 
FXScintilla in a few likely places -- but for now you have to manually 
configure those directories as shown.

Hope this helps,

Lyle
