User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:7.0.1) Gecko/20100101 Firefox/7.0.1 Build ID: 20110928134238 Steps to reproduce: From bug 686305 comment 2, I tried downloading jsshell-win32.zip and jsshell-win64-x86_64.zip, tried extracting each of them into their own subdirectory, and tried running js.exe. Neither one worked, and gave the error "the program can't start because mozutils.dll is missing from [my] computer. Try reinstalling the program to fix this problem.". What am I missing, and where can I find mozutils.dll if in fact I need it?

Needs a packaging fix: http://mxr.mozilla.org/mozilla-central/source/toolkit/mozapps/installer/packager.mk#92

There are two options, really: either include mozutils.dll, or stop linking jsshell to it. Do we have a reason to specifically want jsshell to use jemalloc?

Note: with the landing of bug 414946, the same issue will hit mac, too. Whichever route we take, we can remove the #ifdef in packager.mk, zip will only complain about missing file, but won't fail (iirc its behaviour)

I suspect Spidermonkey hackers will in fact want a JS shell linked with jemalloc.

I spoke to David, he's fine with me taking this bug. This patch simply adds the mozutils library to the archive file containing jsshell.

I built a try-server version at https://tbpl.mozilla.org/?tree=Try&rev=2b9b32464d81 and tested Linux, Mac OS X, and Windows jsshells and they all run without asking for mozutils
