bug#29219: CUPS filter still can't access Ghostscript (gs)

[Mekeor Melire]

I added two printers through CUPS' web interface (localhost:631) using
the PPD driver file which I downloaded (from openprinting.org): one
called ljet4 (which calls Ghostscript) and one called Postscript (which
just calls `cat`)⁰. The latter worked.


But although I was expecting commit
1728c411718e3b358c06561d6e80b47d7b331617¹ to fix this issue, when I try
the ljet4² driver, I still get this error in /var/log/cups/error_log³:


    sh: gs: command not found
    Process is dying with \"Unable to determine number of pages, page count: -1
    \", exit stat 3


Is anybody able to reproduce this issue?

How can I be sure that the cups-service I'm running is the recent one
which includes that commit? (I tried pulling guix and rebuilding the
system afterwards and restarting cups-service afterwards.)

What am I doing wrong?
