Yes, I am definately running the latest version and this happened with 1.8.19 as well . I will look for the file in /system/bin and see if its there.
p.s. The file is there, interesting though.. at the top of terminal emulator when it first starts up this is what it says $ export PATH=/data/local/bin:$PATH
so does this mean its pointing to the wrong location hence it can't find the file ?
I am using clean, wiped version 1.8.26.
ditto for me.
