Well, lets say I modified libexpat and it's now different than the one

However, if for some reason the local expat build fails, my check to
compile a small program still works because it picks up the installed
one on the system.
So add a symbol to your modified libexpat. Link against that symbol in
your source code. Use -no-undefined. Then programs will fail to link
(and on some systems, those where -no-undefined works well, also
libraries will fail to link). Of course you've broken the API now.
Why would it break the API if he simply adds a dummy symbol to make the
difference between stock libexpat and his modified version?
