New description:

 1. Everything goes well with xcode11.0, but when installing gcc9 with
 xcode11.1 it fails (I followed exactly the migration procedure). I have
 the following:

 {{{
 sudo xcode-select --version => xcode-select version 2370.
 xcrun --show-sdk-path =>
 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk
 }}}

 2. Then I tried to install gcc9

 {{{
 .....

 Error: libgcc9 cannot be built while libunwind-headers is active.
 Error: Please forcibly deactivate libunwind-headers, e.g. by running:
 Error:
 Error:     sudo port -f deactivate libunwind-headers
 Error:
 Error: Then try again. You can reactivate libunwind-headers again later.
 Error: Failed to build libgcc9: libunwind-headers is active
 Error: See

 for details.
 Error: Follow https://guide.macports.org/#project.tickets to report a bug.
 Error: Processing of port gcc9 failed
 }}}

 3. I desactivated libunwind-headers

 {{{
 houzeaux:/Users/houzeaux/Desktop % sudo port -f deactivate libunwind-
 headers
 Password:
 --->  Deactivating libunwind-headers @5.0.1_0
 --->  Cleaning libunwind-headers
 }}}

 4. I reinstall gcc9 and get the following message:

 {{{
