[Pluto-help] configure PHP

[Paolo Alberti]

Dopo aver installato MySQL e Apache
(./configure --prefix=directory --enable-shared=max), ho provato ad
installare PHP4 con il comando:
#
./configure --with-apxs=apache_directory/bin/apxs --with-mysql=mysql_directo
ry
Ma alcune cose non vanno:

checking for working aclocal... missing
checking for working autoconf... missing
checking for working automake... missing
checking for working autoheader... missing
checking for working makeinfo... missing
checking whether to enable maintainer-specific portions of Makefiles... no
checking for bison... no
checking for byacc... no
configure: warning: You will need bison if you want to regenerate the PHP
parsers.
checking whether the C compiler (gcc) is a cross compiler... no
checking for AIX... no
checking for flex... no
checking for lex... no
./configure: flex: command not found
checking for flex... lex
checking for yywrap in -ll... no
checking lex output file root... ./configure: lex: command not found
configure: error: cannot find output from lex; giving up

Ho riportato solo quel che non va.
Mi manca qualcosa? Uso gli rpm? Se si, come disinstallo MySQL e  Apache che
comunque vanno bene?
Vi ringrazio e ciao a tutti.
