	I don't know what is "standard" in MacOSX, but I'd suggest you to
have a /usr/local/bin in your PATH (before any other) and install all
additional packages, such as POV-Ray, in there.  This has the advantage
to avoid messing up the system.  Moreover I guess this is what is
recommanded by the FHS (filesystem hierarchy standard).

	For the reasons above, the answer is "no"  :-)

	In principle you can easily add the /usr/local/bin path in the
default PATH environment, either as root or as non-priviledged user.
In the case of tcsh, you should add  'setenv PATH /usr/local/bin:$PATH'
in either /etc/csh.cshrc or /etc/csh.login (as root) or in ~/.cshrc
~/.login (as user).  Consult the tcsh manual ('man tcsh', in section
"Startup and shutdown") for further details.

	Good  ;-)

	If you have /usr/local/bin in your PATH as discussed above, you
will not need to use the --prefix option for any package that uses the
GNU configure scheme (which nowadays is the de facto standard for source
packages).
