[mapserver-users] GDAL TIFF fun - two supposedly identical builds....

[woodbri at swoodbridge.com]

Antti,

Do a ldd on mapserver and the php_mapscript.so on both boxes and see 
if it reports any differences. What OS are you running these boxes 
under. If Linux they might have different versions of rpms loaded.
