It's not recommended for a reason. You really shouldn't.

First, did you run ldconfig after installing vala (you have to do that as
root)? It might be that you do actually have /usr/local/lib in
/etc/ld.so.conf, but the dynamic linker does not list the directories at
start-up of every program, relying on having the listing in /etc/ld.so.cache.
Since new vala version installed new library, you have to update that file by
running ldconfig.

I have default /etc/ld.so.conf (in Debian) and it *DOES* contain
/usr/local/lib, so running ldconfig might help.

If it does not than I suppose autotools stopped generating rpath for some
reason. You can force it by adding it to LDFLAGS (at configure time).  I am
not sure whether you need to pass it as "-rpath=/usr/local/lib" or
"-Wl,-rpath=/usr/local/lib" though. It is basically equivalent to defining
LD_LIBRARY_PATH, but applies to the binary rather than to a session.
