    77In that installation, in macports.conf, I added these two settings:
    88{{{
    9 #KEN
    109macosx_deployment_target     10.13
    1110macosx_sdk_version           10.13
    1211}}}
    13 I put a copy of the MacOS 10.13 SDK in the proper location where MacPorts would find it. I believe it is correct to put it here:

    1514/Library/Developer/SDKs/MacOSX10.13.sdk
    … …  
    2019}}}

    22 Then I found, when trying to build a few port +universal, that the plumbing of the SDK to the linker was not always happening correctly. Also, sometimes the linker would put out a warning that 32bit builds were going away, and this would generate an error in some link steps. I stopped those issues with a minor modification to `portconfigure.tcl` in that /opt/universal MacPorts installation.

    33 After that, almost all the ports would install +universal on that system without any trouble. A few ports were not plumbing the `-isysroot${configure.sdkroot}` to the build and link line, three or four, and I tagged that bit onto the compiler spec, most often by adding a bit like this to the portfile:
    34 {{{
    35 if {${configure.sdkroot} ne ""} {
    36     configure.cc-append   -isysroot${configure.sdkroot}
