Additionally, some shells only expand "~" at the beginning of a "word", so if you `export PATH=~/foo:~/bar' the second "~" won't be expanded. (bash will expand it after a colon, so that should work.)
Do you perchance know which shells would expand only the first tilde?
Older zsh when MAGIC_EQUAL_SUBST isn't set. zsh 4.x handles "export" and some other builtins automatically, but MAGIC_EQUAL_SUBST is still needed in some cases, such as the occasionally suggested `echo PATH=... >>.profile'.
A way to check this: type `env PATH'.
Shouldn't that be
It was supposed to be "printenv". *sigh*
If the result contains a "~", you need to look at how you're setting PATH to make sure "~" isn't being quoted.
If the result contains a tilde, you're already hosed because System.Directory.findExecutable doesn't do tilde-expansion before calling doesFileExist.
