No need to reinvent the wheel. :-) The package "stow" is meant to do
just that for packages in /usr/local.
If you don't mind compiling the flightgear sources manually (perhaps by
reading the ebuild and doing it yourself), then compile it to install
in /usr/local/stow/flightgear-x.x.x, compile and install. Something like
this:
First:
emerge stow
Then:
tar xzf flightgear-x.x.x.tar.gz
cd flightgear-x.x.x
./configure --prefix=/usr/local/stow/flightgear-x.x.x
make && make install
cd /usr/local/stow
stow flightgear-x.x.x
The alternate method is to emerge flightgear as binary packages and
install back and forth like that.
Stow-like functionality would be really cool in portage, I agree.
