Hit the compile error (global not defined) when loading commit a84b680 into a GemStone stone using Rowan. The missing class is not referenced in the src-gs .gs files, so the src-gs files may not be up to date ..... I replaced the reference with lookup code ((Rowan classNamed: 'GtPhlowView') and was able to load all of the Rowan code (gtoolkit-remote and gtoolkit-gemstone).
I was able to successfully connect to the GemStone db and run all of the snippets...
