When I tried to update the cURL to cURL 7.31.0 today for my FreeBSD, it stopped and gave the following error messages:

configure: using CFLAGS: -O2 -pipe -DLDAP_DEPRECATED -fno-strict-aliasing
configure: CFLAGS error: CFLAGS may only be used to specify C compiler flags, not macro definitions. Use CPPFLAGS for: -DLDAP_DEPRECATED
configure: error: Can not continue. Fix errors mentioned immediately above this line.
===>  Script "configure" failed unexpectedly.
Please report the problem to [email protected] [maintainer] and attach the
"/usr/ports/ftp/curl/work/curl-7.31.0/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/sbin/pkg_info
-Ea).
*** [do-configure] Error code 1

It is very simple the fix this problem. However, the prerequisite is to give up the support to LDAP. If you are not sure whether your cURL needs LDAP or not, you probably don’t need it.

cd /usr/ports/ftp/curl
sudo make config

Remove the LDAP related features, such as LDAP, LDAPS. Try to re-build cURL again.

sudo make clean
sudo make

If everything looks good (i.e., not complaining any more), you can resume the update process, e.g.,

sudo portmaster -Da

Now your FreeBSD should be happy.
