[Proftpd-devel] Build proftpd 1.3.5 on RHEL6

[Plots P. <plo...@gm...>]

Hi all,
I'm trying to build a stable RPM for RHEL6 of proftpd and proftpd ldap
module.
I'm dealing with an unexpected issue. My rpmbuild fails with

cpio: proftpd-1.3.5a/.libs/proftpdS.c: Cannot stat: No such file or
directory
cpio: proftpd-1.3.5a/lib/libltdl/.libs/libltdlcS.c: Cannot stat: No such
file or directory

I suspect a problem with "libltdl" that is not present when building 1.3.4.
Does anybody have an idea around this?

Thanks
L
