Comment (by felixs):
The build system proposed in http://wiki.sagemath.org/BuildSystemSEP
(#14796), provides options to disable packages (and falling back to
already installed things outside of sage). also sage (the library) needs
to work without the distribution.
Finally, under some circumstances, sage --PROGRAM needs to just use plain
$PATH. And it always should.
So lets solve this problem at its root:
* sage (the distribution) places a dummy into $SAGE_LOCAL/bin/p for all
enabled packages p, if such a file doesnt exist (or more dummies if
needed)
* installation of a package will replace these dummies
* sage (the distribution) clears these dummies upon disabling a package
(which also triggers uninstall)
* sage (the environment) just sets PATH=$(SAGE_LOCAL)/bin:$PATH (as it
currently does)
* sage (the library) works outside sage (the distribution) without
headache
To deal with even more paranoia, sage (the distribution) could also
include a list of header and library locations for each package. Placed in
a similar way, respective files could make sure gcc won't fall back to
/usr/include or /usr/lib without your consent.
