Description: pgAdmin III v1.4.1 fails to compile with GCC 4.1.0
Details:

"emerge =pgadmin3-1.4.1" produces the following errors with GCC 4.1.0:

pgadmin3-1.4.1/src/include/pgSchema.h:88: error: extra qualification
'pgSchemaObject::' on member 'pgSchemaObject'
pgadmin3-1.4.1/xtra/pgagent/include/connection.h:44: extra qualification
'DBConn::' on member 'DBConn'

Removing the extra qualifications allows the build to succeed.
