Gstreamer Issue

[cdaher78]

I've built from source using gst-build (branch 1.18.0) and this is the error I'm getting:

** (python:1127): WARNING **: 11:57:16.753: Failed to load shared library 'libgstrtspserver-1.0.so.0' referenced by the typelib: /usr/lib/arm-linux-gnueabihf/libgstrtspserver-1.0.so.0: undefined symbol: GST_CAT_DEFAULT

    self.server = GstRtspServer.RTSPServer()
TypeError: could not get a reference to type class

rtspServer exited with code: 1```
 
Anyone faced some similar issue? 

I don't know how to solve this.
