[Pharo-users] Error when trying to initiate Pharo in Ubuntu 64 bits

Hi, I downloaded pharo 3.0 for linux. Since I'm using Ubuntu 11.10 64bits, I've installed the ia32-libs as the readme file says, but when I run ./pharo the following error is shown: /pharo3.0/bin/pharo: /lib32/libc.so.6: version `GLIBC_2.15' not found (required by /pharo3.0/bin/pharo) What's missing? Thanks in advance.
