I was looking at the output of 'env' when perl524 was enabled and
verified that when having LIBRARY_PATH set in the shell, the library
is being found.

It would require further testing to find out if setting LD_LIBRARY_PATH
makes a difference.

However, I even created a symlink to the library and it still couldn´t
be loaded, so this is just weird.

It needs to at least present a warning it decides to override things
explicitly set by the admin, like in a unit file.

Anyway, I´ve given up on this, and the current plan is to use a VM or
another machine with a different distribution to provide the service.
That will probably be Debian, and we have a VM running Debian anyway,
so I might just use that.
