Not critical but looks very ugly and should probably be fixed for 1.3 
I see this when installing a test binary built as an rpm.
[root@testhost ~]# rpm ivh /some/path/to/maxscale-1.2.1.8-x86_64.rpm

This looks quite ugly and broken.
Note the rpm install actually works but this looks like it needs some attention, if not now, at some later point in time.
Seen on RHEL/CentOS 6.
Also notice the rpm name generated from cmake .. -LH -DPACKAGE=Y -DWITH_MAXSCALE_CNF=N; cmake ..; make package is not correct. Again a minor thing but it would be good to make it look normal, maybe something like:
maxscale-1.2.1.8-1.el6.x86_64.rpm
I think that using -DWITH_MAXSCALE_CNF=N should not be necessary. The rpm spec file should configure /etc/maxscale.cnf as %config ... (noreplace) etc.
Basically the rpm generation needs a bit of love.
That said the library setup obviously upsets /sbin/ldconfig so that really should be resolved.
