Can not build on Centos 6 with mono 3.0.2: libzmq exists, but couldn't be found

[Syjgin]

I have installed mono from source and zeroMQ from repositories, so it exists on /usr/lib64/libzmq.so.1
When attempting to build clrzmq there are many errors like this:

1. ForwarderDeviceTests+WithADeviceSubscription (ZeroMQ.AcceptanceTests.DeviceTests.ForwarderDeviceTests+WithADeviceSubscription)
   System.TypeInitializationException : An exception was thrown by the type initializer for ZeroMQ.Interop.LibZmq
