Gorm and gormtool 1.4.1 abort() on startup: Unknown protocol version

This is on OpenBSD, amd64, following packages installed:

gnustep-back-0.31.0 GNUstep gui backend
gnustep-base-1.30.0p1 GNUstep base library
gnustep-gui-0.31.1  GNUstep gui library
gnustep-libobjc2-2.2.1p0 GNUstep libobjc2 objective-c runtime
gnustep-make-2.9.2  GNUstep makefile package

Installing using OpenBSD ports/packages framework, as well as installing from source, Gorm aborts with:

Unknown protocol versionAbort trap (core dumped)

Gorm 1.3.1 starts up all fine.

here a start from within gdb:
