When compiling DBD, it seems that you must specify an ORACLE_HOME. But what if you have multiple homes, of different releases (e.g., 9.2 and 10.1)? Our testing shows that when you compile DBD for one of these homes, then you run into trouble using perl for the other home. Is there a way to compile the DBD such that perl will pick up the ORACLE_HOME from the users environment -- during runtime?
