Has the libPi3API.so been build? Has the PHP interpreter itself really
been build? If not, build PHP4 and then Pi3Web (read the instructions in
Pi3Web/Source/PHP4/README how to get and build PHP4). The single needed
steps are roughly:

1.) download and unpack the Pi3Web source distribution
2.) download or checkout the appropriate PHP4 source distribution
3.) copy the PHP4 files into Source/PHP4, i.e. you can find, e.g.
     Source/PHP4/PHP4/CREDITS

            ^^   This is the PHP script interpreter source tree *)
            ^^
            This is the location of the Pi3Web PHP4 wrapper **)

      *) after steps 2.) + 3.)
     **) the Pi3Web sources doesn't contain the PHP sources but only
     some needed wrapper code

4.) build PHP4 interpreter
    (cd Source/PHP4/PHP4; ./configure --with-pi3web; make)
5.) build Pi3Web
    (cd Source; sh ./Build; make)

The linkify script modifies the online documentation generated from
the API sources during the build and adds appropriate hyperlinks to
it, i.e. this is no critical problem.

But it seems again, there are no *.html files in Pi3Docs/APISpec/,
i.e. neither the PiAPI, Pi2API nor the Pi3API have been built yet.

If you get gcc compiler errors or linker errors during the build -
which version of binutils you are using? I built Pi3Web with gcc 2.95
but RH 9 is gcc 3.2.2. I expect, the build will fail with the newer
gcc without some header modifications (currently work on that).

I hope, I could at least clarify the most probable cause of the
