MacPortrait appears to max out at ancient TPD resolutions. Is there a current solution? Windows and Ubuntu have had me spoiled for the longest. 
The last time I ran a second screen in that orientation on a Mac it was the Macintosh Portrait Display on the 2300c/DuoDock+ next to the 21" Radius TPD it shared with the DA a couple of decades ago. Been running on a single screen for my OS9 Graphics Suite for the longest time on the series of G4 PortlyMac upgrades over the years. I'm all the way up to MDD'03 now.
Tried to reorient a second screen from the AGP VidCard, but no joy. Thought it was a single card limitation, but now with a PCI card up and running next to it there still seems to be no option to go Portrait?
BTW, playing with MacPortrait beat the snot outta the Monitors Control Panel. Tried to reinstall it individually from the 9.2.2 CD from OS9Lives, but no go. Good thing I'm setting up a new boot drive tomorrow!
