The GNU C library now includes Michael Glad's Ultra Fast Crypt, which
provides the Unix `crypt' function, plus some other entry points.  Because
of the United States export restriction on DES implementations, we are
distributing this code separately from the rest of the C library.  There is
an extra distribution tar file just for crypt; it is called
`glibc-crypt-2.0.1.tar.gz'.  You can just unpack the crypt distribution
along with the rest of the C library and build; you can also build the
library without getting crypt.  Users outside the USA can get the crypt
distribution via anonymous FTP from ftp://ftp.ifi.uio.no/pub/gnu
[129.240.64.21], or another archive site outside the USA.  Archive
maintainers are encouraged to copy this distribution to their archives 
utside the USA.  Please get it from ftp.ifi.uio.no; transferring this
distribution from prep.ai.mit.edu (or any other site in the USA) to a
site outside the USA is in violation of US export laws.
