Apparently the problem is incompatibility with gcc 4.0 and its handling
of namespaces.  I really do not know what I am doing but I did finally
get BibleTime to successfully compile by making several changes to the
source files.  Here is what I had to do:

in cinfodisplay.cpp before line 47 I added:
namespace InfoDisplay {
and closed the brace at the end of the file.  It seems like the
namespace must be defined in both the declaration and the definition.

Before chtmlreaddisplay.cpp:303 (CInfoDisplay::ListInfoData infoList;),
I added the line:
using InfoDisplay::CInfoDisplay;

In cpointers.cpp:28, I needed to change the signature to:
void CPointers::setInfoDisplay(InfoDisplay::CInfoDisplay* const
infoDisplay)
That is, I needed an explicit reference to the InfoDisplay namespace.

Similarly, I changed bibletime_init.cpp:78 to:
m_infoDisplay = new InfoDisplay::CInfoDisplay(m_leftPaneSplitter);

And bibletime.h:393 to:
InfoDisplay::CInfoDisplay* m_infoDisplay;

Then I successfully compiled.  Hope this helps - John
