Compiling Zaptel on a 2.4 kernel is getting harder, as development seems to focus now more on the 2.6 kernel releases. Compiling the newest Zaptel sources on linux 2.4.33.3 today gave the following errors:
root@baikal:/usr/src/zaptel# make
make[1]: Entering directory `/usr/src/zaptel'

I immediately ran 'updatedb && locate page-flags.h' and the file didn't exist anywhere on the system. I suspected this might be due to the builder expecting a 2.6 kernel to be present, so I just went for broke and tried the following:

1) Download latest 2.6 kernel sources
2) Extract
3) updatedb && locate page-flags.h # this returned a file in the new source tree
4) copy the file into the place where zaptel's build process is expecting it:

$ cp /usr/src/linux-2.6.20.3/include/linux/page-flags.h /lib/modules/2.4.33.3/build/include/linux/.

So I tried the aboce, re-ran make, and the compilation ran through to the end without error. hurrah!
