libphp4.so not generated

[Anon]

Installing program: php-config
Installing program: pear
Installing program: pearize
Installing program: phptar
Installing program: phpextdist
make[2]: Leaving directory /usr/src/modules/mod_perl/php-4.2.1/pear'
make[1]: Leaving directory/usr/src/modules/mod_perl/php-4.2.1/pear'

These are the last lines after make install. No other errors at ./configure or make, make install are visible but libphp4.so is not generated.

Any hint???

Thanks,
CHRIS
