Hmm. Well I cannot get to this failure, because I cannot build mldonkey's dependency lablgtk2 as per #45559.

I see you installed lablgtk2 with the +quartz variant. I didn't. Maybe that's relevant.

I see your mldonkey configure output shows this:

:info:configure checking for native code lablgtk2... no
:info:configure Do you want this script to try to download and install lablgtk2
:info:configure LOCALLY in mldonkey directory ?
:info:configure ./configure: line 9330: read: read error: 0: Bad file descriptor

This makes me think mldonkey is not compatible with lablgtk2 when installed with the +quartz variant. You should report that to the developers of mldonkey so they can fix it, and until they do, you'll have to install lablgtk2 without the quartz variant, and that will probably fail for you as it did for me per #45559.

We should update mldonkey to 3.1.5 when the issues with its dependencies have been resolved.

The lablgtk2 problem has been resolved.

The mldonkey problem remains, even with 3.1.5. The real error is:

:info:build File "src/utils/net/terminal.ml", line 188, characters 2-4:
:info:build Error: This comment contains an unterminated string literal
:info:build File "src/utils/net/terminal.ml", line 188, characters 5-7:
:info:build Error: String literal begins here

This appears to be an incompatibility with changes that occurred in ocaml 4.02. I have reported this problem to the developers of mldonkey for you:

The developers have already fixed this problem 4 months ago but have not released a new version containing the fix.

Applying the fix locally, the next error that occurs is:

Error: The files /opt/local/lib/ocaml/pervasives.cmi
      and /opt/local/lib/ocaml/camlp4/camlp4.cmi
      make inconsistent assumptions over interface Pervasives

I have reported this problem to the developers:

This was a MacPorts bug: apparently it is necessary to rebuild ocaml-camlp4 every time ocaml is updated, and we had not done that after ocaml was updated to 4.02.1 in r127004. I've done it now in r131098. mldonkey now builds. I've updated mldonkey to 3.1.5 in r131099.
