Undefined symbols in libPostGISProvider-3.5.0.so

Description
When the PostGIS Provider is build using configure/make, a number of undefined symbols appear when "ldd -r" is run on the .so file
undefined symbol: PQclear (./libPostGISProvider.so) undefined symbol: PQresultStatus (./libPostGISProvider.so) undefined symbol: PQgetvalue (./libPostGISProvider.so) undefined symbol: PQclear (./libPostGISProvider.so) undefined symbol: PQresultErrorMessage (./libPostGISProvider.so) undefined symbol: PQexec (./libPostGISProvider.so)
undefined symbol: _ZN12FdoFunctionZ6CreateEv (./libPostGISProvider-3.5.0.so) undefined symbol: _ZN12FdoFunctionX6CreateEv (./libPostGISProvider-3.5.0.so) undefined symbol: _ZN12FdoFunctionY6CreateEv (./libPostGISProvider-3.5.0.so) undefined symbol: _ZN12FdoFunctionM6CreateEv (./libPostGISProvider-3.5.0.so)
The first block is due to damaged libpq.a and libecpg.a libraries checked into Subversion. Libraries rebuild from the PostgreSQL 8.4.2 sources work ok.
The second block is due to a missing libExpressionEngine library dependency in Providers/PostGIS/Src/Makefile.am. Adding the missing dependency to Makefile.am fixes the issue.
The undefined symbols prevent the PostGIS library from loading successfully on Linux. The first block of undefined symbols also causes load errors with the PostgreSQL provider.
