gstgldebug.h:28: error: redefinition of typedef 'GstGLAsyncDebug' I chose a different approach from the PR. The trick is that since this is a slave port, the patchdir by default is from the masterport. In my fix, I put the patches back into this port's files/ subdir and do some Makefile magic to invoke them. PR: 233788 (based on) Submitted by: Piotr Kubaj Approved by: portmgr (tier-2 blanket)
