This should not be. Can you give me an example?

The best thing you could do is look at the gpgkeys_hkp.c file in the
GnuPG 1.3.x release.
However, the LDAP servers are becoming more important these days (as
"PGP Universal" has one built in). Rather than just implement HKP,
since you know that anyone using Enigmail has GnuPG installed, why not
call the gpgkeys_xxxx programs directly? That way you get support for
all keyserver types, current and future.
