@isuruf I don't suppose all your recent cleanup work happened to fix this issue as a side effect, did it? In anycase, thank you.

P.S. Do you want to be listed as a maintainer of this recipe?

[isuruf]

I cleaned up the recipe a bit to fix some segfaults and fix #15. Hope you don't mind.
I don't use ocaml myself so I don't see myself maintaining this recipe. I cleaned up the recipe to help another developer who wanted ocaml for another conda package.

[peterjc]

Thank you for solving this @isuruf! Funnily enough the only reason I packaged OCaml in the first place was as a build time dependency for another tool that I wanted in conda (hevea).
