Comment:

 Remember to fill in the Port field and to Cc the port's maintainer.

 The error the user will see in the main.log is:

 {{{
 Checking for C header file alsa/asoundlib.h... no
 Checking for C header file
 /System/Library/Frameworks/CoreMIDI.framework/Headers/CoreMIDI.h... no
 It appears you don't have the required MIDI libraries installed. For Linux
 this means you are missing the development package for ALSA libraries.
 }}}

 alsa does not exist (there is no port for it) but CoreMIDI.h does exist in
 that place.

 On my system I see slightly different output in the config.log (attached)
 than above, centered around:

 {{{
 /Developer/SDKs/MacOSX10.4u.sdk/System/Library/Frameworks/CoreServices.framework/Headers/CoreServices.h:20:6:
 error: #error 64-bit not supported
 }}}

 So it's using the 10.4u SDK when we didn't ask it to, and the 10.4u SDK
 doesn't support 64-bit here, and software builds 64-bit by default as of
 Snow Leopard. So we should tell it to use the 10.6 SDK instead (or, better
 yet, no SDK). Then if it still doesn't support 64-bit here, we need to
 tell it to build 32-bit.
