If you've built using configure, then there is no way to do this. Just 
do a normal "make install" and if you have modified the source file, 
make will work out what to do. You may wish to rename the old executable 
before you do this, so that you can still access both versions.

If you've built using CMake, then make g_hbond should work.

Checkout release-4-5-patches to get the bugfix, or patch it yourself by commenting out line 1497, which reads "return hbNo;":
