Unable to compile GnuPG 2.1 beta 3

[Alphazo]

I'm trying to compile the newly released GnuPG 2.1 beta 3 but it
fails. First I had to update my libassuan to 2.0.3 but now I get this:

make[3]: *** [dirmngr_ldap] Error 1


In the meantime, here are the package I already have installed on my system:
- libldap 2.4.28
- curl 7.23.1
- bzip2 1.0.6
- zlib 1.2.5
- libksba 1.2.0
- libgpg-error 1.10
- libgcrypt 1.5.0
- pth 2.0.7
- libusb-compat 0.1.3
- libassuan 2.0.3
- texinfo 4.13a
- readline 6.2.002
- pinentry 0.8.1

Do I have one the dependency not up to date for building this beta3?

Thanks
