Definitely.
It would be even better to tell the full file name.
e.g. /etc/fpcpkg.cfg.

That's my problem too. That's why I'm asking for a better error message.

It would be extremely helpful, if it would check common mistakes, like
this. An error message "Directory /path/fpmkunit is missing. Check your
/etc/fpcpkg.cfg." would be far better than "Error: the Fppkg
configuration is corrupt."
What is corrupt? Is something missing, too much, not readable, did a
command fail? What did it check to come to this conclusion?

Or if it does not fit into a one or two sentences, you can give a link
"See here how to setup fppkg http://wiki.freepascal.org/...". 

Same with
"Failed to create a new Fppkg configuration. You will have to fix the
configuration manually or reinstall Free Pascal."
What did it try? What command failed?

As root that would overwrite my /etc/fpc.cfg
As normal user it creates /home/mattias/.fpc.cfg

Lazarus does similar checks with fpc. Some fpc version changed some
paths, some platforms have different files. Boom, the user gets a
wrong error message. That's why the IDE should tell exactly, what it
checked.

It guessed the prefix correctly.

Probably it fails because I have old 2.6.4 fppkg configs.
