Installation of claws-mail port fails

[gith-account]

I'm trying to install the claws-mail port on MacOS Sierra 10.12.2.

First I got this warning and error:

Warning: All compilers are either blacklisted or unavailable; defaulting to first fallback option

Attempting to fetch expat-2.2.0_0.darwin_16.x86_64.tbz2 from https://packages.macports.org/expat
Attempting (...)
Error: org.macports.archivefetch for port expat returned: archivefetch failed for expat @2.2.0_0
Error: Failed to install expat

I did the following about the warning:

$ sudo port uninstall mysql5-server
$ sudo port uninstall mysql5
$ sudo port install mysql56

MySQL was installed without a problem.

Now when I try to install the claws-mail port I get this error:

Attempting to fetch gdbm-1.12_0.darwin_16.x86_64.tbz2 from https://packages.macports.org/gdbm
Attempting (...)
Error: org.macports.archivefetch for port gdbm returned: archivefetch failed for gdbm @1.12_0
Error: Failed to install gdbm

I checked ​http://packages.macports.org/gdbm/gdbm-1.12_0.darwin_16.x86_64.tbz2 in the browser and can access it just fine.

I manually tried both:

$ sudo port fetch gdbm
$ sudo port fetch gdbm @1.12_0

Nothing ends up in /opt/local/var/macports/distfiles

Any ideas?

Please attach the main.log file.

Apparently some problem with resolving the hosts. Turning off the firewall did not help. No problems with resolving the hosts and accessing the files in the browser.

Any proxies configured in macports.conf, systems prefs, or environment variables?

Replying to jmroot:

Any proxies configured in macports.conf, systems prefs, or environment variables?

No, and proxies would not explain why it started working after a sufficient number of dependencies had been installed manually. If I understand the information in ticket:50986 correctly this has been fixed in Macports 2.4.0. What irritates me a bit is that "$ sudo port fetch gdbm" did not do anything, but I can live with that.
