Comment (by jvianalopes):

 Thank you very much!
 Your suggestion was very useful.
 I was not using the "port configure" neither the "port logfile".
 Instead, I was copying the build temporary folder and inspecting the
 config.log.

 The difference is in the flag:
 CXXFLAGS='-pipe -Os -stdlib=libc++
 -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX11.sdk -arch
 x86_64'
 removing the -stdlib=libc++ the symbols coincide.
 How can I remove this option with macports?
 I tried to edit the Portfile using the "port edit hdf5" and defining
 CXXFLAGS with configure.env without success.
 Thanks in advance
 João
