Please replace the version number with $fpcversion.

Nice. Just like the existing fpc_crosswin32 package, but finally for
more platforms. :)

Probably because /usr/share/lazarus is set in the environment options as
lazarus directory and you told the IDE to rebuild the LCL.
The LCL can still only be built via the Makefile and this is not very
flexible. Eventually when the LCL is changed to a normal lazarus package
it will be possible to build the LCL, even if the LCL was installed as
root.
