Bugzilla Bug 15763

I'm getting the following error when compiling net-mail/maildrop-1.5.2:

This problem only occurs with "ldap" USE keyword. I've solved it by adding
"-lresolv" to the compilation options for the ldap related code. I've done it
by modifying the ebuild, in src_compile():
51c51
<       emake || die "compile problem"
---
>       emake LIBLDAP='-lldap -llber -lresolv' || die "compile problem"

This works at least on two gentoo 1.2 boxes (default-1.0, gcc-2.95.3,
glibc-2.2.5-r7).

is this still an issue? On a gcc-3 system I just did USE="ldap" and it emerged
fine.

hmm ok, I just tried this with gcc-2.95.3 as well again a successful emerge.

Yes, it's still an issue here:

----
This was using a "Portage 2.0.48-r1 (default-1.0, gcc-2.95.3, glibc-2.2.5-r4,2.2.5-r8)" system.
 
Maybe it's related to the ldap version? In default-1.0 profile, openldap-2.0.27 is masked, so I still use 2.0.25-r2... (and I can't really test 2.0.27 because it needs a readline update which would, I guess, break several things. Am I wrong?)

maildrop-1.5.3 has been added to portage.

I have updated the ebuild with this stanza... I know it's not an elegant fix by any means... but at least it raises awareness for those users with an older profile+ldap...

emake || die "If you enabled java in USE and are running a \   
        1.0 profile box, edit ${P}.ebuild and uncomment the \
        alternate emake line."

# alternate emake line for 1.0 profile boxes
# emake LIBLDAP='-lldap -llber -lresolv' || die "compile problem"
