Hi, I just discovered a new whohas command in Debian, that can show a package in virtually all important distributions (Arch, Debian, Fedora, Gentoo, openSUSE, Slackware (and linuxpackages.net), Source Mage, Ubuntu, FreeBSD, NetBSD, OpenBSD, Fink and MacPorts distributions). So for example SymPy is in a lot of them already: $ whohas sympy Arch python-sympy-git 20090121-1 unsupported http://aur.archlinux.org/packages.php?ID=23341 MacPorts py-sympy 0.5.15 http://trac.macports.org/browser/trunk/dports/python/py-sympy/Portfile MacPorts py25-sympy 0.6.3 http://trac.macports.org/browser/trunk/dports/python/py25-sympy/Portfile FreeBSD py25-sympy 0.6.3 math http://www.freebsd.org/cgi/pds.cgi?ports/math/py25-sympy NetBSD py-sympy 0.5.15 math http://pkgsrc.se/math/py-sympy Ubuntu python-sympy 0.4.2-1 universe http://packages.ubuntu.com/gutsy/python-sympy Ubuntu python-sympy 0.5.8-1 universe http://packages.ubuntu.com/hardy/python-sympy Ubuntu python-sympy 0.5.15-1~hardy1 universe http://packages.ubuntu.com/hardy-backports/python-sympy Ubuntu python-sympy 0.5.15-1 universe http://packages.ubuntu.com/intrepid/python-sympy Ubuntu python-sympy 0.6.3-1 universe http://packages.ubuntu.com/jaunty/python-sympy Debian python-sympy 0.6.1-1 testing http://packages.debian.org/lenny/python-sympy Fink sympy-py24 0.5.6-1 http://pdb.finkproject.org/pdb/package.php/sympy-py24 Fink sympy-py25 0.5.6-1 http://pdb.finkproject.org/pdb/package.php/sympy-py25 Gentoo sympy 0.6.3 http://gentoo-portage.com/dev-python/sympy Gentoo sympy 0.6.2 http://gentoo-portage.com/dev-python/sympy openSUSE python-sympy 0.6.3 science http://packages.opensuse-community.org/packageinfo.jsp?checksum=a2258d3deaee... It's also interesting to click on the links to get to the pages of sympy for each distribution.
