You can use a second config directory. The --pcp option tells the IDE
and lazbuild what config directory to use. Default is $HOME/.lazarus.

Make a copy of your .lazarus (e.g. .lazarus2)
Change the paths in .lazarus2. For example via the ide:

./lazarus --pcp=~/.lazarus2

Then you can rebuild the IDE with:

./lazbuild --pcp=~/.lazarus2 -B --build-ide=

The widgetset gtk2 is the default since 0.9.27 so you don't need to
give that option.
