Ciau Florindo,

I think your problem is not really in the php_mapscript.so, but in the gdal 
library which php_mapscript.so is trying to load dynamically (see the third 
line of the warning, which starts with 'libgdal.1.1.so').
GDAL has been dynamically linked into mapserver, so each time mapserver or 
mapscript runs, it will load libgdal.1.1.so. To be able to do this, it uses a 
program called ld (the dynamic linker). You can check which libraries a 
program or other dynamic library depends on with the following command: ldd 
<programname>, e.g. 'ldd php_mapscript.so'. Try this and it will show you 
that is uses libgdal.1.1.so, and where ld has found this library. In your 
case, probably ld has *not* found it, so it will tell you this.
Now (hopefully) the solution to your problem:
1) you need to run 'ldconfig' after you 'make install' a library, like gdal or 
gd. This updates the dynamic linker internal database.
2) this only works if the needed libraries are in ld's search path. So if 
simply running ldconfig does not work, check the paths in /etc/ld.conf. The 
paths with your libs should be in there.

Btw, Steve Woodbridge recently updated the mapserver wiki page for building 
mapserver/mapscript on redhat. See: 
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?RedHat8AndMapserver37 . You 
might find these notes helpful.

Btw2: If I remember well, the php configure option 'use-system-regex' has been 
canged into '--with-regex=system'. The old option might still work (well, it 
seems to as you did not receive an error message on that while compiling 
mapscript), but to be shure you might want to use the new option.

Well, era una storia lunga...
I hope it helped you. Otherwise, send a message to the list again :)

Regards,
Vincent Schut.
