There I see only the 64 bit libs, I will try to ask in some ubuntu forum 
if I can install also the 32 bit libs without destroying  the server (as 
I did yesterday cause I moved with "mv" a lib that was required by "mv" 
itself, restoring it this morning with a live cd).

Also now I have that error while linking at 64 bits (even if I 
reinstated the original configuration/situation):
/usr/lib/fpc/2.2.1/units/x86_64-linux/rtl/cthreads.o: In function 
`CTHREADS_LOADPTHREADS$$BOOLEAN':cthreads.pp:(.text+0x11): warning: 
Using 'dlopen' in statically linked applications requires at runtime the 
shared libraries from the glibc version used for linking

reference to `__dlopen'
/usr/bin/../lib/libdl.a(dlclose.o): In function `dlclose': undefined 
reference to `__dlclose'

PoolPatrol.lpr(185,1) Error: Error while linking
PoolPatrol.lpr(185,1) Fatal: There were 1 errors compiling module, stopping

That's probably the end of that computer lazarus installation, I can't 
risk to mess up the libs again.

Thank you for the support, it's a pity that I was so close.

p.s. the wiki guide should be a little updated.
