php install Linux - bison

[rantnrave]

I'm installing php as a dynamic module on Mandrake 8.0 with Apache 1.3.27 already running. The

configure

bit fails with a message telling me that bison needs to be installed:- but bison is installed, at

/usr/bin/

. There doesn't seem to be a

--with-bison=/usr/bin/

option, but I tried it anyway. It didn't work.
It also says that it can't find output from

lex

. Is that related to flex?
I have bison 1.75 and flex 2.5.4a installed. I assume they are the latest versions, as they were the highest numbers I could see at the GNU site an hour ago.
Any ideas?

Okay: bison wasn't at

/usr/bin/

but had put itself at

/usr/local/bin/[code]. So that bit now works.

However, the [code]apxs

script/program fails. I have put the path to it :

/usr/local/apache/bin/apxs

, which is the only

apxs

I can find. The installation notes say to not use the apxs version in the apache sources. Does this count as being in the apache sources?

The configure script fails with that message saying that perl might not be installed (it is), the

mod_so.c

might not have been compiled (it was) or that apxs cannot be found. However, it also says the apxs coudn't be succesfully run and then provides the apxs help menu - which isn't particularly helpful - suggesting that it has found apxs.
Any ideas?
