[Modules] mod_dbi_pool and libdbi coudn't found

[Marcel Hartmann]

Hello List,

i have a Problem with libdbi and mod_dbi_pool.

The module mod_log_sql is compiled in correctly and i use it now.

But if i compile mod_dbi_pool on my CentOS4 System, i get the following
errors:

checking for dbi Includes in yes/include... no
configure: error: *** libdbi not found!

so i installed this:
$yum install libdbi libdbi-devel

after this i have in /usr/include/dbi/ this: dbd.h  dbi-dev.h  dbi.h

Now i compile the mod_dbi_pool against this dbi like this:

$./configure --with-apxs=/usr/sbin/apxs --with-dbi=/usr

the configure script adds the path /include/dbi/... to the given prefix.
And now he find the libdbi but says error again!

checking for dbi Includes in /usr/include... found it! Use --with-dbi to
specify another.
checking for libdbi library in /usr/lib... yes
checking for dbi_version in -ldbi... no
configure: error: *** libdbi not found!

He says he found it, and then he told me to specify another libdbi.
In the configure script it looks like this:

# Check whether --with-dbi or --without-dbi was given.
if test "${with_dbi+set}" = set; then
  withval="$with_dbi"
  dbi_path="$withval"

fi;

# Determine dbi include directory.
if test -z $dbi_path; then
    test_paths="/usr/include"

    test_paths="${dbi_path}/include"

  echo $ECHO_N "(cached) $ECHO_C" >&6

  ac_check_lib_save_LIBS=$LIBS
LIBS="-ldbi  $LIBS"
cat >conftest.$ac_ext <<_ACEOF
/* confdefs.h.  */
_ACEOF
cat confdefs.h >>conftest.$ac_ext
cat >>conftest.$ac_ext <<_ACEOF
...

Has anyone a idea to solve my problem?
My libdbi is version -> libdbi-0.6.5-10.RHEL4.1

Is this the wrong version for this modules?
