Configure error for cyrus-sasl2-saslauthd after upgrade

[Robert Fitzpatrick]

I upgraded a FreeBSD 8.4 server to 10.1 and all went well for the most 
part except I can't get saslauthd to build now. I run saslauthd with the 
ldap flag and if I use the binary package install, it complains the ldap 
is an unknown mechanism. So, I remove the binary package and when I try 
to build from ports....

configure: error: in 
`/usr/ports/security/cyrus-sasl2-saslauthd/work/cyrus-sasl-2.1.26':
configure: error: C compiler cannot create executables
See `config.log' for more details.
===>  Script "configure" failed unexpectedly.
Please report the problem to ume at FreeBSD.org [maintainer] and attach the
"/usr/ports/security/cyrus-sasl2-saslauthd/work/cyrus-sasl-2.1.26/config.log"
including the output of the failure of your make command. Also, it might be
a good idea to provide an overview of all packages installed on your system
(e.g. a /usr/local/sbin/pkg-static info -g -Ea).
*** Error code 1

In the config.log, this is the error section.....

I have tried to force rebuild of all ports using portupgrade and applied 
all Freebsd updates, rebooted, still get the same error. I've searched 
for a solution on the web, but can't find anything specific to my error. 
Can someone please tell me what I might be able to do to solve this 
issue? Other packages build fine, I've removed cyrus-sasl and rebuilt to 
no avail and many other packages.

Thanks, Robert
