Gee, what a setup!
I have learned from the ML (somebody could confirm) that mixing tiff
and gdal is not good: so if you use gdal then say --without-tiff.
I see that you have some mapserver libraries installed in
/usr/local/mslibs: how do you make sure that mapserver picks those up
instead of the system provided (gd,png,tiff for example)?
Then do you really need php/python/tcl/wfs/postgis/oracle/wcs? If not
disable the ones that you do not use, this will reduce the likeliness
of mapserver/mapscript errors (I'd recommend to take a conservative
approach when using Java mapscript).
HTH,
