I can not give a better error-message, if I do not even know myself what 
the problem of your configuration is.

It already does all checks I can think of. And it does have special 
messages for all those cases.

But, as long as I do not know what the problem is that you or others are 
experiencing, I can not give a better message.

The message you see is the last message, when it failes but the system 
has no clue why.

Maybe I should change this message to what is exactly happens, that it 
can not find the rtl. But this was the message in the past, leading to 
all kind of complains like: 'But the RTL is just there!'.

We have to find the right message. It also took a while until we found 
the right text for the other problems in this dialog.

But first I have to know what your issue actually is.

When it can not find those files, it will tell you so. Just like the 
other screens do. Just type something on the combobox with the prefix, 
it will give you hints until the path is probably right.

It should be able to handle those. And even when not, fpcmkcfg should 
just overwrite those.

Another guess would be: it uses an old version of fpcmkcfg. Older 
versions need other parameters for it to work. But it seaches for 
fpcmkcfg at the same location it finds the compiler. So when you did do 
a 'make install', it should use the latest version.

How do your fppkg.cfg and default files looks like? After the re-create 
that is?
