Thanks Fang,

So, if I am reading your question correctly, the question is whether
bison is relocatable.  The answer is no, it is not, it is meant to
be used where it is installed, as most Unix tools.

However, there are a few environment variables (such as LD_LIBRARY_PATH,
etc.) which you may tweak to have Bison work from elsewhere.  Have
a look at the tests/bison script for a start in the distro, it can
be a starting point to write a wrapper.

I would however suggest to use a real packaging system instead.
If you can.

Cheers.
