Install the development package (containing phpize command):

apt-get install php5-devel (or whatever it is called)

Looks like you don't have compiler installed. I believe it goes
something like this:

apt-get install build-essential

Once you're done, do to ext/interbase and run 'phpize'. Maybe you don't
have to if you already have 'configure' script there, but then it
doesn't look like vanilla php5 source?

./configure --with-interbase=shared,/path/to/firebird
make

You'll find the interbase.so file in .libs directory.
