Comment (by ryandesign@…):

 Thanks. So this is interesting.

 Here's what my log has happening at the beginning of the destroot:

 {{{

 And then it continues on. Here's what yours says:

 At which point it has failed.

 The line starting with `version=` is complicated and deserves some
 analysis. First, it tries to use `git` to determine the version of code
 being built. If that fails (for example if the code being built is not
 from git but from a release tarball, which is the case in MacPorts) then
 the string "wine-1.5.16" is used. (This string is presumably inserted into
 the code at the time the release tarball is produced.) The string from the
 preceding step is then wrapped in a line of C code, which assigns it to
 the C constant "wine_build". This line of C code is assigned to the shell
 variable "version". This shell variable is compared with the contents of
 the file "version.c". If they are not identical, the shell variable is
 written into the file. If writing the file fails, the file is deleted and
 the script exits with an error.

 In `make`, a file is automatically rebuilt if any of its dependencies have
 changed since it was built. version.c is used to build version.o, and
 version.o is a dependency of libwine. In my log, after running the command
 that begins with `version=`, nothing else happens. version.o and libwine
 are not rebuilt. This is what we would expect, since version.o and libwine
 have already been built in the build phase, and the version of code has
 not changed since then. But in your log, version.o is rebuilt, and then it
 tries to rebuild libwine and fails, saying wine_build is not defined. This
 tells us that the command that begins with `version=` did in fact change
 version.c in your case, thus triggering version.o to rebuild. It also
 shows that version.c did not get generated correctly this second time.

 Could you attach the file
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports
 .org_release_tarballs_ports_x11_wine-devel/wine-
 devel/work/wine-1.5.16/libs/wine/version.c so that we can see what ended
 up inside it?

 Also, could you run the following command and tell us what output, if any,
 it produces:

 {{{
 echo `(GIT_DIR=../../.git git describe HEAD 2>/dev/null || echo
 "wine-1.5.16") | sed -n -e '$s/\(.*\)/const char wine_build[] = "\1";/p'`
 }}}
