I guess in this case you could have your script put /usr/local/bin at a higher precedence in your $PATH (or QV) and then test (or not) the version at runtime. by using "sed' and not "/path/to/sed" this would allow a more graceful failover on a new system (with a new sed) I dont forsee any problems with that except for portability. if you specify /usr/local/bin/sed and move the script to another box you have to remember to move sed.

I was trying to install sed so I could develop a script to be used on an ancient Sun server with an ancient version of sed that doesn't even know about extended regex, as far as I can tell. It doesn't have a manpage or even an option to display the version. At least if you give it an option it doesn't understand it spits out the minimal "usage" message. So anyway, thanks for the suggestion about installing an older version of sed to build the latest version. I don't think that ever would have occurred to me. I'm surprised that the sed developers didn't realize there were different versions of sed with different options and write the configure script to recognize the rather predictable errors and respond to them by trying other options. Also, I was going to go ahead and install sed in /usr/local/bin and keep it out of the default command path, assuming that there are probably cron tasks and other system utilities that depend on sed -E. Have you run into any issues there? I also got that error.

I found this while trying to do the same thing for the same reasons. Wouldn't have thought to install an old version of sed. Thanks!
