FreeBSD mirror and some issues with Perl (with suggestion for change!)

[Espen Tagestad]

From the documentation on how to set up a FreeBSD mirror: 
http://www.freebsd.org/doc/en_US.ISO8859-1/articles/hubs/mirror-howto.html

... there is a paragraf written like this: 
"ftp/mirror was very popular, but seemed to have some drawbacks, as it is written in perl(1), and had real problems with mirroring large directories like a FreeBSD site."

Beeing a user of both FreeBSD and Perl for years (and probably for years to come) I don't find this formulation providing Perl any justice. What's the issue with Perl? That it has to be installed additionally? I don't care about the mirror program itself (I went for the rsync way). Would it be a less drawback if it was written in Ruby or Python?

Suggestion for change:
"ftp/mirror was very popular, but had real problems with mirroring large directories like a FreeBSD site."
