Jailing Apache and APR/APU

I'm Rock-Linux (a distribution buildkit) jailing subsystem mantainer. (
http://www.rocklinux.org/sources/misc/jailing/ )
I'm using DESTDIR=$jail (ex. DESTDIR=/jail/apache/ ) to install apache 2.0.x
into jail root.
This works good but in many (quite all) scripts (usually APR/APU related)
paths need to be rewriten.
Some example:
apxs
apr-config
apu-config
apr_rules.mk
config_vars.mk

My rewrite code (not latest version) is here
http://www.rocklinux.org/sources/mis...kage-functions .

Without this code (long to be complete) ex. php can't build using apxs2 and
with INSTALL_ROOT=$jail (same jail as apache).


Is there a better way to make apr/apu scripts have correct paths than sed
mass-usage?

yours,
