Peter Simons 1e575d3572 perl-5.8 and perl-5.10: fixed build on MacOS X
On MacOS X, we used to use the native perl interpreter from /usr/bin.
Unfortunately, that interpreter fails to build a number of packages
(Subversion, Git, etc. ...), because it assumes knowledge about the
underlying C compiler that is not valid for the compiler used by Nix.
For example, /usr/bin/perl assumes that the compiler can build binaries
for both the ppc and the x86 architecture. /usr/bin/gcc can do that, but
the gcc from Nix can't.

The solution is to compile Perl 5.10 in Nix so that the ./configure
phase can properly detect the system's capabilities. However, note that
the resulting binary is impure: it will find headers in /usr/include and
libraries in /usr/lib. In this respect, the Nix-compiled perl binary is
no different than the native one in /usr/bin -- it's just configured
more accurately.

# This patch does the following:
# 1) Do use the PATH environment variable to find the `pwd' command.
# By default, Perl will only look for it in /lib and /usr/lib.
# !!! what are the security implications of this?
# 2) Force the use of <errno.h>, not /usr/include/errno.h, on Linux
# systems. (This actually appears to be due to a bug in Perl.)
