[Lazarus] Startlazarus starting "wrong" Lazarus

[Juha Manninen]

If both versions are in the system path then anything can happen.
The one you install from RPM goes maybe to /usr/bin/ and is certainly
in the path.
I recommend you put any other version of Lazarus into its own
directory which is not in the system path,
for example into "~/Lazarus_test". Then start it from console:
 $ ./lazarus --pcp=~/.lazarus_test
