 "Warning: More than one default port source is defined. Warning: The macOS
 11.2 SDK does not appear to be installed. Ports may not build correctly.
 Warning: You can install it as part of the Xcode Command Line Tools
 package by running `xcode-select --install'. --->"

 Regarding the above error, the following mail archive link tells me to
 ignore it because I tried everything too (from
 https://trac.macports.org/wiki/BigSurProblems).

 Also can you clarify the following for me? Sorry i am new to bashing mac.

 When you say "remove my branch after the test", do you mean that after
 editing the sources.conf file I write in mac terminal

 sudo port -v sync

 Then i open sources.conf and remove the line
 [​file:///opt/local/var/macports/sources/github.com/macports/macports-
 ports/]

 And then I type back in mac terminal

 port configure gwyddion

 port -v build gwyddion
