revdberr,invalid database type - ODBC - library not loaded

[Robert Eppich]

Mac OS X 10.5.1(powerPC), Rev 2.8.1 I keep getting the error:

"revdberr,invalid database type"

using the function:

revOpenDatabase("ODBC","Remote_EBCO_ODBC","","userName","password")

ODBC Administrator is configured and tests correctly, as does 'Get  
External Data' > 'New Database Query...' in MS Excel.

Using other database types, like MySql, works fine, but ODBC always  
returns " invalid database type.

My console shows this error indicating a library was not loaded.

Any ideas how to fix this? I have downloaded and re-installed Rev  
2.8.1 without success.

Thanks
