Uh, yeah, this was an easy fix once I realized what was going on.
Hopefully at least my silly confusion leads to a Google-able answer
for someone in the future.
$ sudo easy_install --upgrade pygments
Got me the right pygments version.
Thanks, sorry for the bother.

Yeah, sorry, I was typing a correction when I saw your email come in:

Sorry, scratch that. On the box I used above, I had some stuff
leftover from Pygments HEAD. Therefore it's confusingly talking about
1.5. The Racket lexer was added between Pygments 1.5 and 1.6. You need
the Pygments 1.6 re
OK, my version looks like yours, but seems to have less taste in languages:

First let's make sure your Pygments version is new enough to include
the lexer for Racket.
Can you try the following and let me know what it says, for you?

I need to distribute to students using vanilla 5.3.6.
Should I expect the binaries to be compatible?
Can I create a 5.3.6 binary package by hand somehow?
The problem I am actually trying to solve is to provide students with
some functionality with

I'd like to create a package that includes only compiled code, no source code.
I don't see a suitable option on 'raco pkg create'. Is this possible?
If so, how should it be done?

1. W/o files, I can only guess that you're using a partially ported initdr. scm

Hi,
I've been using EOPL2 to teach Programming Languages for a dozen years now,

Thanks, I'll leave that lesson for another day! I've reverted back to using
the non-typed predicate. I had originally done this as the first step to
solving a chaperone problem with a hasheq being seen as a hash, but that
was a bug with 5.3.6 since fixed in the git master branch, but switching to

guess is a procedure, and not a number.
The error message is telling you that it expects a number and not a procedure
as the argument to sub1.
If you evaluate guess in the REPL, you can see the problem:

Thanks Matthew for adding the new abstract URL!
I updated travis-racket to use this. In your build matrix you can now
specify `HEAD` as well as versions like `5.3.6`.
For example this .travis.yml runs a build against 3 versions of
Racket, 1 of which is HEAD:
