Updates: Status: InvalidComment #1 on issue 3735 by marcus.d...@gmail.com: ODBCLibrary class moduleName calls deprecated method
http://code.google.com/p/pharo/issues/detail?id=3735
This is not a bug of Pharo... but the ODBC package. Can you send it to the author of that package?
As a workaround, you can turn off deprecation warnings in pharo (see Settings).
