On this page I am collecting ideas on how to make pkgsrc work in even the most horrible environments.

Setting up a horrible environment

/bin, /sbin and /usr are missing completely.
All tools work at the lowest requirements (limited line length for sed and awk, a minimal shell).
Somewhere at the front of the PATH, there is a directory that has all possible tools in it, but they don't work, so pkgsrc really is forced to make use of the tools wrapper.
Low limit for the length of the command line (see IRIX for a good example).
Set PKG_CONFIG_PATH to ${LOCALBASE}/lib/pkgconfig, so that pkg-config finds all the packages installed, although it was supposed to not see them.
echo exploits the possibility for implementation-defined behavior if the first argument is -n or there is a backslash in any argument.
