Trying to execute LibcxxOnOlderSytems (3rd ed.)

[ftp83plus]

Ok, I changed the topic to reflect the new attempt. MacPorts has been uninstalled as per instructions, and reinstalled. I am now attempting to run https://trac.macports.org/wiki/LibcxxOnOlderSystems in order to support software that may be written according to C++11 standard.

I ran step 2 as corrected. No error reported.
I ran step 3.1. No error reported at either step (3.1.1 and 3.1.2).
Edited /opt/local/etc/macports/macports.conf as per step 3.2:
The beginning of the file now looks like:
cxx_stdlib         libc++
buildfromsource    always
delete_la_files    yes
default_compilers  macports-clang-3.4 macports-clang-3.3 gcc-4.2 apple-gcc-4.2 gcc-4.0

# $Id: macports.conf.in 117120 2014-02-17 00:55:33Z jmr at macports.org $ […]

Then step 3.3. Received:
Error: No ports matched the given expression
I assumed it was normal since this is a fresh installation, no port has been inactivated by step 3.1.1.

Then step 3.4: was long and noisy, but received no error.
Then step 3.5: no error
Then step 3.6: no error
Then step 3.7: It says to edit /opt/local/etc/macports/macports.conf again ; mine now looks like
cxx_stdlib         libc++
buildfromsource    always
delete_la_files    yes
default_compilers  macports-clang-3.7 macports-clang-3.4 macports-clang-3.3 gcc-4.2 apple-gcc-4.2 gcc-4.0

# $Id: macports.conf.in 117120 2014-02-17 00:55:33Z jmr at macports.org $

As I understand it, this is the last step.

Then I tried to install Xsane, but it failed; I will open another thread so as to keep this one clean.
