FWTools is deliberately intended to avoid conflicts with system libraries
and other applications.  If you use the approach of adding the
FWTools/bin_safe directory to your path, then the only conflict should
be with regard to deciding which executable to run (/usr/local/bin/gdalinfo
or FWTools/bin_safe/gdalinfo for instance) which will be determined by
order in the path.

The bin_safe executables setup their own environment, forcing use of
FWTools shared libraries.

At no other time should the FWTools libraries interfere with anything else
on your system.

The situation is different if you source the fwtools environment setup
scripts (fwtools_env.csh or fwtools_env.sh).  If you do this, you run
substantial risk of cross polination in ways likely to be bad.  I normally
only do this on an otherwise quite clean system.
