No, waf does install jackd to /usr/local and there shouldn't be any
issues even if you install to /usr, since we only build jackd. While
when building JACK1, it does check for an already installed JACK, JACK2
IIRC doesn't test, if there's already a version of JACK installed. IIRC
the known issue with building and installing JACK is, that there might
be 2 versions of JACK installed, so JACK won't work. Installing dummy
packages will remove existing files and installing by waf should be ok.

Correct, for checkinstall you manually can add dependencies, they aren't
included by default.

Checkinstall won't work, because it will replace 'make install' and
doesn't work with waf. Handling dpkg in this case isn't self-explaining,
building dummy packages can be easily done by equivs. But full ACK, if
somebody has the knowledge to build a 'complete' package this is the
best solution.

Hm? Someday I'll try this for JACK.

PS: Right now I'm doing an Ubuntu version update from 10.10 Maverick to
11.04 Natty. I did backup the current install ;). Perhaps self-compiled
software and third-party packages will cause trouble.
