I tried all this, and finally installed all the stuff successfully.  After
that (and after configuring the Apache conf files) I got the following:

varan101!root:~# apachectl start
*** glibc detected *** free(): invalid pointer: 0x800c0ae8 ***
/usr/sbin/apachectl: line 102:  5692 Aborted                 $HTTPD
$OPTIONS -k $ARGV
varan101!root:~# 

As far as I understand, such a thing, happening to a well-tested stable
package, should mean a shared libraries incompatibility.  At this point I
decided not to follow this way any further; fortunately all the things
happened within a OpenVZ container so that I could just shut down the VPS
and create another one from scratch.  It would be too complicated to
reinstall the real machine, and it is tricky to restore the status quo
after lots of packages were installed and some of them even downgraded the
existing ones.

If anyone from Openwall is interested, I can either provide the archive of
the container or even bring it back up and grant the root access to it.
However I'm in doubt whether this can be of any use.

Errr... I continue to think it is a wastage of time to try making foreign
packages work under Owl.  I should have spent this day compiling Apache
from the sources instead -- I think it could give me better results.

I don't think this 'issue' worth the time you're going to spend fixing it.


Thanks for trying to help, though.
