Arrgh...

Sorry I didn't realize that I had the following local change

Index: ogrct.cpp
===================================================================
RCS file: /cvsroot/osrs/gdal/ogr/ogrct.cpp,v
retrieving revision 1.23
diff -r1.23 ogrct.cpp
138c138,140
< #ifdef WIN32

Note you can set an enviroment variable to the proj DLL name

in the same file see 
LoadProjLibrary() {
....
    if( getenv("PROJSO") != NULL )
        pszLibName = getenv("PROJSO");

HTH
