Hello Nicolas.

Done

> some games still fail to run, e.g., phantasia and hack.

Pity.  What errors are output?

How i do start the games:

cd git/guix
guix environment --pure guix
./bootstrap && ./configure --localstatedir=/var && make -j2
./pre-inst-env guix environment --ad-hoc bsd-games
phantasia
--->
   Guix: Please set up the BSD_GAMES_DIR variable.
   Examples:
      export BSD_GAMES_DIR=/var/multiplayer
      export BSD_GAMES_DIR=~/.local/share/bsd-games
   You can place this in ~/.bashrc or a similar file for Your shell.
   For multiplayer this directory should be writable for all players.

BSD_GAMES_DIR=~/bsd-dir phantasia

+David Leverton writes about adventure/crc.c:
+
+The 'adventure' game from the games-misc/bsd-games-2.13 package crashes
+when saving the game on AMD64 (and probably other 64-bit systems, but I
+haven't checked).  Find attached to fix this.
+
+http://bugs.gentoo.org/show_bug.cgi?id=77032
+
+
+About utmpentry.c:
+
+the utmpx structure defines the ut_tv member a little differently on
+64bit hosts so that a 32bit and 64bit structure can be shared.  So the
+ut_tv is a custom 32bit structure rather than the native 64bit timeval
+structure.  Work around is to assign the submembers instead.
