--------------------+--------------------
 I'm building a fresh install of MacPorts on a fresh install of Big Sur
 11.6.2 with a fresh install of XCode 13.2.1

 Running "./configure" I get this:

 {{{checking for Tcl public headers... configure: error: tcl.h not found.
 Please specify its location with --with-tclinclude}}}

 Yes I ran Xcode, and built something with Xcode, and also ran all these
 commands:
 {{{
 $ sudo xcode-select --install
 $ sudo softwareupdate --install -a
 $ sudo xcodebuild -license
 $ sudo xcode-select --reset
 }}}

 looks like Xcode command line tools installed Tcl stuff here:

 {{{
 % sudo find /Library -name tcl.h
 /Library/Developer/CommandLineTools/SDKs/MacOSX11.1.sdk/usr/include/tcl.h
 /Library/Developer/CommandLineTools/SDKs/MacOSX11.1.sdk/System/Library/Frameworks/Tcl.framework/Versions/8.5/Headers/tcl.h

 /Library/Developer/CommandLineTools/SDKs/MacOSX12.1.sdk/System/Library/Frameworks/Tcl.framework/tclConfig.sh
 }}}

 As per the find results above, Yes I did try these commands:
 {{{
 $ ./configure --with-
 tclinclude=/Library/Developer/CommandLineTools/SDKs/MacOSX11.3.sdk/System/Library/Frameworks/Tcl.framework/Versions/8.5/Headers
 $ ./configure --with-
 tcl=/Library/Developer/CommandLineTools/SDKs/MacOSX11.3.sdk/System/Library/Frameworks/Tcl.framework/
 }}}
 And I also tried using both --with-tcl and --with-tclinclude together and
 in all cases I get some variant of this message at the top
 {{{
 configure: WARNING: unrecognized options: --with-tcl, --with-tclinclude
 }}}

 I'm guessing that the latest MacPorts is not tested with Big Sur 11.6.2
 and Xcode 13.2.1. I have reasons for needing to use Big Sur and not the
 latest OS Monterey. For the "--with-*" params, I chose the MacOSX11.3.sdk
 because that's the closest version to what I'm using but it's moot because
 in all cases "./configure" doesn't seem to be passing these params down to
 the tcl config script.

 Please help, I was hoping to make my own build rather than use the
 prebuilt binary .pkg installer

 thanks
