Yes, probably.  Can you tell us in which way purify ought to be invoked
when libtool is not involved?

Likely, something like this should work:
  ./configure CC='purify gcc'

but it will probably be rather slow; so to speed it up, you might want
to try replacing the last command with
  make CC=gcc CCLD='purify gcc'

if you don't need to run purify during compilation.  That still makes
for an awful slow configure (so a --config-cache should be beneficial
for reruns).

If you don't need to use purify during creation of shared libraries,
then you can probably g et away with something like
  ./configure CC=gcc
  make CCLD='purify gcc'

(all of this is assuming GNU make, BTW; otherwise use something like
  env CCLD='purify gcc' make -e

BTW, if there are any issues, can you please post the libtool version
that Apache 2.0 uses (./libtool --version)?
