Bug 507675

# SUMMARY

The installation BaSH script for `kdesrc-build 22.07 (v22.07-699-g5c2db76c)` does not install `perl-IPC-Cmd` and `perl-JSON-PP` on `PRETTY_NAME="Fedora Linux 42 (KDE Plasma Desktop Edition)"`, despite `--initial-setup` requiring these dependencies.

After its installation, but when `perl-JSON-PP-4.16-513.fc42.noarch` is absent:

After both have been installed, it installs the remnant absent RPMs.

# EXPECTED RESULT

These dependent RPMs should be installed during initial installation. One (not of these) was, so these are merely absent from its dependency list.

# SOFTWARE/OS VERSIONS

Of `kde-builder`:

> ~~~
> RokeJulianLockhart@Beedell:~/projects/kde/src/kdesrc-build$ ./kdesrc-build --version
> kdesrc-build 22.07 (v22.07-699-g5c2db76c)
> ~~~

If that's not specific enough, due to my method of installation:

> ~~~
> RokeJulianLockhart@Beedell:~/projects/kde/src/kdesrc-build$ git rev-parse --verify HEAD
> 5c2db76cd0f9a6b373e1fe9d106b3354733d18f1
> ~~~

Of the DE and OS:

> ~~~
> Operating System: Fedora Linux 42
> KDE Plasma Version: 6.4.3
> KDE Frameworks Version: 6.16.0
> Qt Version: 6.9.1
