Yes. For some reason, system(...) returns false whenever there is > in
the command. Maybe, in the future, the functionality of mpto can be
incorporated into (new)texexec. This is not needed right away, as I
managed to get rid of the mess in my system by using cygwin binaries
for ruby.

Turns out that the problem is not with the one click installer. It has
to do with the fact that I also had cygwin installed (even though I
was using cmd.exe for tests). I have installed cygwin ruby and
everything (at least everything related to context) work fine.
The conclusion seems to be that for windows either:
i) If you do not use cygwin, use any precompiled port of ruby
or
ii) If you have cygwin, use the cygwin port of ruby
or
iii) Compile your own binaries. :)
I am still confused on why windows ruby have trouble with cgywin being
present, but I will leave debugging that to future. Right now,
newtexec is working correctly.
