[racket-dev] Patching a distribution

I am trying to create a patch for 5.0.1 in the form of a plt file that
will backport fixes to plai. To do this I also need to backport the
new define-struct.

I am getting bugs after installation about bytecode mismatches. I'm
wondering if I am doing this correctly and if there is a better way of
doing this?

I put everything in a folder called collects with the correct inner
structure, and then run the following command to make the plt file.

raco pack --at-plt --all-users --replace ++setup racket ++setup plai
plai.plt collects

and then (with a fresh install from the 5.0.1 debian.sh package)

drracket plai.plt (choosing to install the plt file).

Run drracket again and I get the message:

Error invoking tool
#<path:/home/endobson/plt/plt/collects/slideshow>;("tool.ss")

link: reference (phase 1) to a variable in module
("/home/endobson/plt/plt/collects/mzlib/unit.rkt" . 1) that is
uninitialized (phase level 1); reference appears in module:
"/home/endobson/plt/plt/collects/framework/main.rkt" in:
make-rename-transformers

 === context ===

Clicking past this I get a 'link: module mismatch'  error and a frozen
drracket. The plt file is attached.
