Oh yes. The Perl documentations comes with things like perlos400 or perlvms that details the specific problems or advantages people looking to run Perl on that particular platform will face, and the list of these OS-specific documents is really impressive. There are systems on it that run Perl that I have never heard of (or only in whispering, at a New Moon). Perl lets you pretend that Windows know how to fork. That alone still amazes me in a way. During my training, I had to set up BIND 9 on IBM mainframes running z/OS and configure TSIG (cryptographically verified zone transfers), which among other things required changing the (shared) keys on a regular basis (about once per month, I think) and distributing them across about half a dozen systems. Fortunately, at that precise point in time, I stumble across a news headline that IBM just released Perl 5.8 for z/OS and managed to get the sysprog to install it. The alternative would have been REXX. I looked at it, quickly, and then looked away, very determinedly. I was really glad Perl was available on those machines.
