All,

  With kchmviewer, the configure fails with the following:

<snip>
Please remember to use GNU make, often installed as gmake.

Install prefix : /opt/trinity
KDE support    : disabled.
Qt includes    :
Qt libraries   :
chmlib to link : system
checking if lib should be compiled... yes
checking if po should be compiled... yes
checking if src should be compiled... yes
checking that generated files are newer than configure... done
configure: error: conditional "include_x11" was never defined.
Usually this means the macro was only invoked conditionally.

  OK, which macro should be checked and in what file?
