Hi François,

Thanks for updating midworld and keeping an eye on it!

Hacking system headers is not ideal. :)  It may break other software,
and it requires root access.  Perhaps there is a better way.  I compared
the 10.3 and 10.4 SDKs looking for 'scalb' and there are many insights. 
The 10.4 SDK contains this nugget in wxPython_int.h:

#ifdef __WXMAC__  // avoid a bug in Carbon headers
#define scalb scalbn
#endif

I suggest we do the same, it is probably most correct, as it made it
into the 10.4 SDK.  Patch attached.  I can't test on 10.3, but I will
commit it anyway if no one objects.
