Hi,

you must not have a part of your base system on a partion
other than /. If you compile programms that are part of your
base system with gcc-3 you need to have the libraries in your
root-partition. 
The time you installed gcc-3 ist was a kind of add-on, because
you did not need it for any part of your base system. Therefore
it was OK to have it on /usr/local.
Reinstall gcc-3 on / or compile LVM with gcc-2.9x. You may
also do a ldd on every binary you need from LVM and copy
the libraries over to /lib.

cu,
Jan
