against the right dynamic libraries. set-env.sh add the right linker flags to the
NIX_LDFLAGS environment variable, which is passed by gcc-wrapper to the linker.
(In many cases these flags could just be passed through LDFLAGS to configure
scripts; however, in many other cases this doesn't work properly.)

* Disabled gtkspell support in pan since it (and it alone) has a conflict with the
system glibc.
* Use CPU detection in MPlayer so that it also works on systems with different CPUs
than the build system's.

the build and execution environment.
This is very useful. For example, it allows packages built on a SuSE
8.2 system to run on a SuSE 8.1 system (this is because 8.2 has a newer
glibc; packages built against it cannot be dynamically linked against
older glibcs).
Of course, Fix packages should not directly import glibc since that is
very system-specific. Rather, they should import stdenv/stdenv.fix and
in their build scripts source in $stdenv/setup, which will setup the
right environment variables. The idea is that stdenv.fix provides the
basic C/Unix build environment (C compiler, POSIX utilities, etc.).
Note that only the ATerm package currently uses this.

* A solution to the library abstraction problem (i.e., if
package X needs library Y, and library Y needs library Z,
then we do not (generally) want to declare Z as a input to X
since that would break abstraction). This was not possible
under the old Nix.
