I think your inc-prefix is wrong.  When you did "make install" on
libotr, it should have installed the header files into
$HOME/include/libotr/*.  Since pidgin-otr is trying to open
<libotr/version.h>, your -I should be $HOME/include.  So try passing
that to --with-libotr-inc-prefix, and see what happens.
