I must be very sleepy already... it is not makeskel, but fpcmkcfg. The 
options there in the help should be a lot more intuitive ^^ (makeskel is 
for the documentation tool fpdoc).

Oh yes, it doesn't interpret "~"... -.- You can use "$HOME" instead, 
that works ^^

And it's normal for the compiler and its utilities to disallow a space 
between parameter name and it's value (makes parsing of the parameters a 
bit easier).

You might try the following (you need Lazarus 0.9.29 for this) - this it 
not tested by me though:

* Set the compiler in "Settings->Settings->Environment" to 
"/home/???/LazarusInstaller/fpc240/bin/fpc" as suggested by Mattias
* Open a new project and go to 
"Project->Projectsettings->Compilersettings->Others" and add the 
"-Xp(...)" parameter into that memo
* Enable "Use this settings as default for new projects" (or similar, 
I'm using the German version)
* close dialog with ok
Note: existing projects must be adjusted manually
