at a customer's site, but it requires the use of an external library. They were OK with installing a pre-built binary (gzip lib), but refused to load a compiler onto their production box (a 5.0 Tru64 machine). The only available pre-built binary was part of a larger suite that was only available on CD...not much use when I was only on-site for a couple of days. A pure-perl gzip would have been very handy indeed.
