This happens because 3rd party class libraries install themselves as
ABC extensions. The ABBLDEXP.TPW template generates entries for them
in data DLL EXP file because it's the place ABC library is exporting
from. If 3rd party class libraries are not provided with sources, i.e.
they available as DLLs, they will not be compiled and as result the
linker can't resolve names listed in the EXP file.

2 solutions are available:

1) If the class library is supplied with ????L.LIB file (with library
   code compiled and linked in local mode), this file must be added to
   the data DLL project file. Perhaps, some plays with values of flags
   used in LINK() and DLL() attributes of 3rd party classes are required.
2) ABBLDEXP.TPW file could be changed to exclude export of 3rd party
   classes. Look for ";Start of TopSpeed ABC library exports" text in
   the TPW file to find a place where ABC classes export is generating.
