Error running mysql-proxy from source (ibmysql-chassis.so.0)

[Tom M]

G'day,
I've been trying to get the rw-splitting.lua script to work but the read queries haven't been going to the proxy-read-only-backend-addresses even after creating lots of connections to the proxy:4040
I was using mysql-proxy-0.6.1 from Ubuntu's apt.
After reading a thread here recommending to use 0.7.2 to get query splitting working, I decided to compile & install from source (no binary for debian at this stage).
Compile goes fine but when I try to run mysql-proxy I get this error message

mysql-proxy: error while loading shared libraries: libmysql-chassis.so.0: cannot open shared object file: No such file or directory

This is bizarre because a locate shows that the files are there
~# locate libmysql-chassis.so.0
/usr/local/lib/libmysql-chassis.so.0
/usr/local/lib/libmysql-chassis.so.0.0.0


Any tips? Thanks!
