ld64 @97.17_3 build fails on Leopard - can't find libunwind headers

[khepler]

Build of ld64 aborts due to "File not found" errors for the libunwind includes. This is a clean install of Leopard on a PowerMac G5.

The headers are definitely installed:

[PowerMacG5:~] kris% port installed libunwind-headers
The following ports are currently installed:
  libunwind-headers @35.3_0 (active)
[PowerMacG5:~] kris% port contents libunwind-headers
Port libunwind-headers contains:
  /opt/local/Developer/SDKs/Darwin9.sdk/usr/include/libunwind.h

Looks like the Macports SDKs aren't in the paths.

full build log

Was able to build by adding the following line to a relevant section of the portfile:

    configure.cppflags-append   "-I/opt/local/Developer/SDKs/Darwin9.sdk/usr/include"

What's the proper way to add this include path to the port? I can supply an updated Portfile once I figure out how to avoid that absolute path.

Replying to khepler@…:

Probably something like what I just attached​. Can you try it?

Build succeeds with the changes. Thanks!
