cyrus-sasl-saslauthd-2.1.26 auth_krb5.c compile error
Upgrading cyrus-sasl-saslauthd-2.1.25 to the current cyrus-sasl-saslauthd-2.1.26, I started to get auth_krb5.c compile errors that were terminating the compile like:

with some expert advice from the port maintainer, Hajimu UMEMOTO (what is not to love about BSD and open source? Something goes wrong, the guy who knows everything about it tells you how to fix it right away). He correctly ascertained that I had security/krb5 installed, a dependency of openssh-portable. Kerberos, HEIMDAL and GSSAPI occasionally have interactions, but his advice was to make with the directive KRB5_HOME=/usr/local. I put this into /etc/make.conf to make it permanent, deinstall/reinstalled security/krb5 and then cyrus-sasl-2.1.26 compiled perfectly.
Thanks Mr Umemoto!
Postie Image Resize Seems Broken
I updated Postie for the first time in many years, and it seems my fix for ImageMagick is now obsolete, but another fix may be necessary.
It may be that Postie just doesn’t like the FreeBSD environment. The ImageMagick fix was mostly to point Postie’s hard-coded targets to BSD standard locations. This time through I haven’t found the right code yet as postie-functions.php has been completely rewritten.
Fixing ImageMagick resize in Postie
I noticed that postie was doing a terrible job at resizing images.
It turns out that the default GD library isn’t super good at resizing – it does a simple subsample and the result is quite jaggy (see the GD version of this image in this post)
I think the version above looks a lot better. It should have been as easy as just turning on the “use ImageMagick” function in the postie config, but it wasn’t that simple. Two files were not where they were expected to be. The easy one is “convert” which postie expects to find at /usr/bin/convert, but under BSD is actually at /usr/local/bin/convert. This isn’t a big deal as there’s a config option to point postie in the right direction. A bit harder is ImageMagick identify which postie expects to find at /usr/bin/identify, but for which there is no config entry.
The fix for BSD is to edit around line 1768 of postie-functions.php and change /usr/bin/identify to /usr/local/bin/identify before the first run or by resetting postie to defaults. If you’ve already installed postie and don’t want to reset the defaults you may need to edit the postie config database (I did) using, for example, PHPMyAdmin and set the value of IMAGEMAGICK_IDENTIFY to /usr/local/bin/identify.
And thus one gets nice, pretty postie thumbnails.
