Comment(by jhpalmieri):
How widely available is `pwd -P`? The GNU version of `pwd` does not
recognize the `-P` option, but its man page says
{{{
NOTE: your shell may have its own version of pwd, which usually
super‐
sedes the version described here. Please refer to your shell’s
docu‐
mentation for details about the options it supports.
}}}
This is what it says on sage.math, for example. I use bash there, and the
built-in pwd supports the `-P` option. But do we need to worry about
systems where there is no built-in pwd, and it is relying on the GNU
version? I have access to one such machine, and `pwd -P` doesn't work
there, but I've never tried to build Sage on it.
