Offhand, I think apxs -q SBINDIR is returning an invalid result to the configure script. Garbage in, garbage out. Don't have my Mac with me at the moment, but I suspect it's version-specific anyway.

[ryandesign (Ryan Carsten Schmidt)]

According to ​https://github.com/macports/macports-ports/pull/1505#issuecomment-377296795 it only happened on the macOS 10.12 / Xcode 8.3 Travis CI builder; it did not happen on the OS X 10.11 / Xcode 7.3 builder nor on the macOS 10.13 / Xcode 9.3beta builder.

I don't recognize the path /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.12.xctoolchain; I don't have that on my macOS 10.12 system. But there are some Google results for it.

I guess what this ticket points out is that shibboleth is trying to use the copy of Apache included with macOS, and that has been deprecated for awhile. It should probably use the MacPorts apache2 port instead.

[ryandesign (Ryan Carsten Schmidt)]

I can, in any case, reproduce this error on macOS 10.12:

$ /usr/sbin/apxs -q SBINDIR
/usr/sbin
apxs:Error: /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.12.xctoolchain/usr/local/bin/apr-1-config not found!.

[scantor (Scott Cantor)]

I wasn't aware it was deprecated, and if I just outright changed it, that would break anybody currently relying on the port. Can't really do that, so I guess it needs a variant that would specify a macport Apache version and apxs location to use. Of course apxs still has to work. ;-)

[ryandesign (Ryan Carsten Schmidt)]

Well Apple's deprecation of Apache begins all the way back in OS X Mountain Lion v10.8. That's when Apple removed Personal Web Sharing from System Preferences.

[scantor (Scott Cantor)]

There's a 3.0 SP coming soonish that would likely bump the portname to avoid conflicts so that would be a good time to change the default behavior.

[scantor (Scott Cantor)]

This was essentially dealt with in the V3 port, which now uses the port of Apache and I just added a fix that should address locating the right script.
