Update to the last comment by me:
As a result of the BLFS svn repo changing from all bz2 to original package format, now there is no need to name the file "perl-modules.orig.md5sums". The file is now simply "perl-modules.md5sums". It is available here still:
ftp://ftp.lfs-matrix.net/pub/blfs/svn/perl-modules/perl-modules.md5sums
And the tarball of all the original-format packages are also available:
ftp://ftp.lfs-matrix.net/pub/blfs/svn/perl-modules/perl-modules.tar.bz2
Of course, substitute your favorite mirror.
Re-assigning back to blfs-book as my part is finished and I don't know who will update the book.
