hpijs (gutsy) depends on two shared libs of hplip: libhpip.so.0 &libhpmud.so.0

Dependency to package hplip is in hpijs not implemented.
Without hplip you get no warning from package manager.

But when trying to print cups says foomatic-rip failed:
--------------------------------------------------------------------
/var/log/cups/error_log
[..]
(/usr/lib/cups/filter/foomatic-rip) stopped with status 3!
[..]

foomatic manually started says:
-----------------------------------------
$ foomatic-rip -P LaserJet_4P -v test.ps
[..]
hpijs: error while loading shared libraries: libhpip.so.0: cannot open shared object file: No such file or directory
GPL Ghostscript SVN PRE-RELEASE 8.61: Can't start ijs server "hpijs"
**** Unable to open the initial device, quitting.
renderer return value: 1
renderer received signal: 1
[..]

ldd on hpijs says the hole truth:
----------------------------------------
[..]
$ ldd /usr/bin/hpijs
       libhpip.so.0 => not found
       libhpmud.so.0 => not found
[..]

Don't call me Sherlock ;-)

At this point I started searching on the internet... ...nothing :-(

But then I tried to install hplip... ...there we go:
-----------------------------------------------------------
[..]
$ ldd /usr/bin/hpijs
       libhpip.so.0 => /usr/lib/libhpip.so.0 (0x00002aaf2ca73000)
       libhpmud.so.0 => /usr/lib/libhpmud.so.0 (0x00002aaf2cc9a000)
[..]

=> Success: Printing function is healed.

Please update package dependencies of package hpijs in Gutsy.
