[Geomoose-users] Curved labels and libgd or gd.

Did the labels appear at all? Were they only horizontal? I'm not sure what you
mean by "like it should". The ANGLE FOLLOW setting was originally intended for
labeling along road segments; it currently does a poor job of labeling streams
with lots of twists and turns. And there are a few issues filed against it in
Maperver's Trac.
As for the loading of DLLs by mapserv.exe, a good tool to use is ProcessMonitor
(http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx). Run it on the
server when you do a pan or zoom to see which DLLs mapserv.exe is try to load.
Best regards,
Brent Fraser
