Comment:

 Replying to [ticket:41056 david@…]:
 > 1) After Mavericks upgrade /usr/include is gone
 >
 > *) FIX: ln -sf $(xcrun --show-sdk-path)/usr/include /usr/include

 `/usr/include` isn't gone, it's part of the command line tools. Revert the
 symlink and install the command line tools using `xcode-select --install`.
 This will also automatically fix MacPorts' `./configure` script which will
 fail to find Tcl without the command line tools.

 > 2) couldn't open
 "/System/Library/Frameworks/Tcl.framework/Versions/8.5/Resources/tclIndex":
 no such file or directory

 This is a red herring. MacPorts does not need this file, yet somehow this
 error message shows up sometimes.

 > *) FIX: make Macports TCL (which is currently 8.6.1) a dependency +
 arrange for Macports TCL to be used instead of system TCL

 That is currently not possible, because MacPorts base is not compatible
 with Tcl 8.6 (due to MacPorts overriding the `try` statement new to 8.6).
 Also using MacPorts Tcl to build MacPorts would create a very simple way
 for users to shoot themselves, which is why we're not doing that, at least
 not without adding additional safeguards.

 > It appears TCL is no longer provided as a Framework in OSX. There is no
 Tcl.framework directory or tclIndex file on the disk anymore.

 Tcl is still available on OS X, but you have to install the Command Line
 Tools in order to build against it.

 Installing the Command Line Tools will also fix the problem you see with
 the GCC build.
