Thanks, this should be fixed in r147.

I just had the same error, using:
- Mac 10.6.8
- Ocaml 4.00.1
- camlp5 6.08

I've tried various suggestions I've found online, but none have worked so far. 
Any tips would be much appreciated. Thanks!

Dear http://code.google.com/u/114450594453066362058/,
  The fix in your case will be to go into the Makefile
and add a specific test for your OCAML_VERSION and CAMLP5_VERSION
along the same lines that I did. This particular logic is not 
robust to modifications to tool versions.

Got it - thanks. Is is possible to be a bit more explicit? I don't have a lot 
of experience in this area. Thanks again!

If you have a look at my patch, you will see I added an expression

-o  ${CAMLP5_VERSION} = "6.06"

which means "or camlp5 version is 6.06"

you need to add the same with your version which is 6.08 this will be around 
line 59 in the Makefile

Now you will realize ocaml 4.00.1 is quite a bit different from 3.12.x I'm not 
sure what will happen, all this patch does is detect the correct file to use.
It does not mean it will work, so good luck, if it goes wrong, try compiling 
with the 3.12.x series of ocaml and try to spot the problem

Great - something similar seems to have worked:

make clean
cp pa_j_3.1x_6.02.2.ml pa_j.ml
make

I'm having other issues now, but they don't seem related to the makefile. 
Thanks again for your help.
