How do you start Lazarus?
Maybe you are starting an old binary?

Yes.
That is your custom version.
Since you installed a newer version as 'system default', the system
default is newer. In that case the "startlazarus" asks which one to
start.

Good.

Check that the IDE is using the correct Lazarus directory (Tools /
Options / Environment / Files / Lazarus source directory). It should be
"/usr/share/lazarus/1.4.2".

If this does not help:
Close the IDE, delete ~/lazarus/bin, start IDE, build normally (you
don't need "clean").

Note:
By default /usr/share/lazarus/1.4.2 should be readonly for users
and only root can write. This is debian policy. Don't change that
unless you have a special case.
