whatever is the matter with wxWidgets --with-X11??

[sdp]

I am trying to build widgets with X11.
I configure as --with-X11 --enable-debug --enable-monolithic --enable-compat22.
My configure says it has to use Motif toolkit. But is that correct? I thought I read that --with-X11 uses a built-in toolkit.

• Configured wxWidgets 2.6.2 for `sparc-sun-solaris2.8'
  
  Which GUI toolkit should wxWidgets use? motif
  Should wxWidgets be compiled into single library? yes
  Should wxWidgets be compiled in debug mode? yes
  Should wxWidgets be linked as a shared library? yes
  Should wxWidgets be compiled in Unicode mode? no
  What level of wxWidgets compatibility should be enabled?
  wxWidgets 2.2 yes
  wxWidgets 2.4 yes
  Which libraries should wxWidgets use?
  jpeg builtin
  png builtin
  regex sys
  tiff builtin
  xpm yes
  zlib builtin
  odbc no
  expat builtin
  libmspack no
  sdl no
  gnomeprint no

and when I do make, I start getting the following types of errors:

from ../include/wx/wxprec.h:13:
../include/wx/chkconf.h:27:32: wx/motif/chkconf.h: No such file or directory

When is the dir motif under wx created and who creates it? Because I don't see any such dir and hence the error.

Any help is appreciated.

thanks,

Some more info:
The code which causes the error i am seeing is from wx/chkconf.h.
This tries to include wx/motif/chkconf.h
But I don't have the motif dir.
