Linking issues with cyrus-sasl, reason for staying on 2.1.23?

[DougPuchalski]

Using iOSPorts with MailCore. I'm linking with libsas2.a and there are several issues with the mac build. Duplicate symbols related to plugins, struct hostent doubly declared, sys/utsname not included. I've patched these at https://github.com/aceofspades/iOSPorts/tree/cyrus_patches. With these patches, I am able to get a clean link of MailCore, libsasl2, libcrypt, and libsasl2.

Can anyone comment on these issues?

Since this version is a couple of years behind (2.1.25 now) I am curious how others are not having this problem, and whether there's been a reason not to update. Doing so did not appear trivial.
