Is there a possibility to use some library temporarily? Icy Tower requires newer libstdc++.so.6 I've got some approach in /opt/meecolay/lib (libstdc++6 4.4.0 or newer) Is it possible to execute this way: normally use the stock libstdc++6 for /usr/lib, but for this single app use the one from /opt/meecolay/lib? EDIT: I tried using the preenv approach, but the libstdc++6 isn't reloaded.
