apxs generates incorrect LoadModule directive.

           Summary: apxs generates incorrect LoadModule directive.
           Product: Apache httpd-1.3
           Version: HEAD
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: Other
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: Mark.Stracey@futuretv.com

If apxs is used to activate a module in httpd.conf, the path to {CFG_}LIBEXECDIR
is checked to see if it begins with {CFG_}PREFIX, and if so then {CFG_}PREFIX is
stripped from the module path in the generated LoadModule directive.  httpd then
sees the relative path and prefixes it with ServerRoot {CFG_}SYSCONFDIR.

If - like many apache installations - the config, log and binary files are kept
in separate directories, then this results in an attempt to load a non-existant
module from ServerRoot/{LIBEXECDIR - PREFIX}.

This behaviour has been seen on Debian Linux 2.2 (apache package version
1.3.9-14) and Solaris (Solaris 8 10/01, package SUNWapch{u|r} version
11.8.0,REV=2000.01.08.18.12)

'Guilty' lines in apxs:

466:    my $dir = $CFG_LIBEXECDIR;
467:    $dir =~ s|^$CFG_PREFIX/?||;
468:    $dir =~ s|(.)$|$1/|;
469:    push(@lmd, sprintf("LoadModule %-18s %s", "${name}_module", "$dir$t"));

The workaround I'm using (in Solaris PHP4 package postinstall script) is to
substitute the value of PREFIX on the apxs command line:

    apxs -S PREFIX=/foo -e -n php4 -a /usr/apache/libexec/libphp4.so
