I'm trying to install dpkg on Snow Leopard. Latest MacPorts version is installed.

sudo port install dpkg
--->  Computing dependencies for dpkg
--->  Dependencies to be installed: lzmautils
--->  Configuring lzmautils
Error: Target org.macports.configure returned: configure failure: shell command failed (see log for details)
Error: Failed to install lzmautils
Log for lzmautils is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_archivers_lzmautils/lzmautils/main.log
Error: The following dependencies were not installed: lzmautils
Error: Status 1 encountered during processing.
To report a bug, see <http://guide.macports.org/#project.tickets>

Log is attached to this ticket. Any idea what's going wrong?

You have installed your Xcode into a directory with spaces ("/Xcode 4"). Don't do that (use "/Xcode4").

configure: error: C++ compiler cannot create executables
See `config.log' for more details.

In your config.log, you'll have a line like: ./configure: line 2702: /Xcode: No such file or directory
