With all due respect, but I think you haven't understood the problem
case Behdad is trying to solve.

It's very simple: packages have a test suite, or developers merely want
to run uninstalled programs, before they install them (in a new place,
or overwriting earlier versions of the programs and libraries).  In
order to ensure the uninstalled program uses only other uninstalled
stuff, one typically sets some variables, for example $PATH,
$LD_LIBRARY_PATH (or equivalents on other systems), tst_aclocaldir (this
is specific to the Libtool package itself), ...

The LD_LIBRARY_PATH thing (but portable) is already handled by libtool.
Why should it not also handle other variables, given that it would be
*very easy to do*?

Thanks,
Ralf
