hp-check uses build time component (cups-config) during run-time check

[Mark Purcell]

hp-check is using a build time component (cups-config) to do its run
time dependency checking. That is the issue.

hp-check doesn't depend on cups-config, Without libcups2-dev it reports
incorrectly (run time -r):

$ hp-check -r
[...]

Checking for CUPS...
Status: scheduler is running
error: Version: (Not available. CUPS may not be installed or not running.)

[...]
Checking for dependency: CUPS - Common Unix Printing System...
OK, found.

As you can see from the results above, without libcups2-dev, hp-check does report
correctly that the scheduler is running, and that the runtime dependency for
CUPS is met. The thing it cannot determine without cups-config is what version
of CUPS we are running.

> WDYT what should we do?

Replace the runtime call on cups-config with something that will give the
version of the installed CUPS.

Unfortunately none of the binaries shipped with cups appear to report their
version:

cups:
/usr/sbin/cupsd
/usr/sbin/cupsfilter

cups-client:
/usr/sbin/lpadmin
/usr/sbin/cupsaddsmb
/usr/sbin/lpinfo
/usr/sbin/lpmove
/usr/sbin/cupsctl
/usr/sbin/cupsaccept
/usr/bin/cancel
/usr/bin/lpstat
/usr/bin/lppasswd
/usr/bin/cupstestdsc
/usr/bin/lpoptions
/usr/bin/cupstestppd
/usr/bin/lp
/usr/sbin/reject
/usr/sbin/accept
/usr/sbin/cupsreject
/usr/sbin/cupsenable
/usr/sbin/cupsdisable

I would suggest with discuss with CUPS and get an Version string printed out,
possible against; lpinfo and/or cupsd -t.

In the meantime we should downgrade the runtime check from an error to a warning.

Hi Mark Purcell,
You are correct. I will apply the patch.

Thanks!
