I'm now using a completely brain-damaged way to have two 3.x python(1)s
installed: symlinks; i.e. 3.2rc2 is ~/usr/opt/.py-3.2rc2 and tip is
~/usr/opt/.cpython.  Whenever i need to test the thing i'm working on
in my free time with the old version i'm temporarily replacing a
~/usr/opt/py3k symlink (which points to .cpython otherwise).
(I'm doing this because only py3k is in $PATH, $LD_LIBRARY_PATH etc.,
but like i said...)

I don't know if you consider this to be misbehaviour, but a
moment ago i've run the test suite on an installed python(1) tip
and got these symlink-path is not --prefix-path related errors,
just if anyone is concerned (stripping output a bit):

This sounds even more silly now, but i can't reproduce the problem 
any more! 
I could do so easily this noon, before i've opened this issue! 
You *do* see the tracebacks!

I wanted to (try to) write a patch (use os.path.realpath()), but 
even with drop of __pycache__'s, complete recompiles and 
reinstallations: i can't reproduce these faults. 
I've neither updated my repo, nor have i done anything else. 
The options are the same, too (python3 -E -Wd -m test -r -w). 

I leave this issue open until tomorrow noon, maybe someone with 
glue reads it and has one or two minutes to give me a hint on what 
is happening here.  (Thank you!) 
I'll close it, then?!

So, nobody.  I still can't find a way to reproduce the errors, so.
I also get occasional errors when building _multiprocessor, which
disappear when (removing _multiprocessor_failed.so and) simply
running make all once again.
I thought about providing the patch anyway, but it is maybe better
to simply close this issue (in the meanwhile).

It happened again.

The very same messages as in msg130452!
I'll try to write a patch which uses realpath() this evening
or so, and if this works i'll upload it.
Someone should take care about that, then, i think ...

B-) -- now this:

Signore Melotti, i'm making you nosy because you're the one
which committed to this file last (db7385).

I've tried a bit to write a patch, but my simple os.path.realpath()
solution didn't work.  I've got no idea of the test framework,
nor of the tracer, so i'm the wrong person here anyway.
(It would have been interesting why test_trace.py fails when run
as part of the test suite, but succeeds if called directly,
even from within the same directory.)
Once again i attach failed test output.

Please decide if this issue is to be closed or not,
i can't help at all.
