Did you include txr as an input to your package? The 'patch-shebangs doesn't 
patch in an absolute path to an env utility: it rewrites shebangs to use the 
absolute path to the actual interpreter, in this case txr, and it only does so 
if the interpreter is actually present at build time. (A package source might 
contain scripts that aren't actually used, and they shouldn't create artificial 
dependencies.)
