WebSharper error when building under Mac OS X

Question

I'm trying to build a project using WebSharper under Mac OSX and I got the following error :

I can build the same project under Windows without any problems. Under windows I can simply do msbuild or specify a configuration msbuild /p:Configuration=Release or even the Fake compiler. And under Mac OSX whatever I try to use (using xbuild or Fake) I always got the same error. Last time I had that I was able to build the project using Release mode but here it's not working either.

I have hosted the project under github : https://github.com/MangelMaxime/BugReport

I know it's not recommended but better to have the same conditions...

Looks like a Cecil bug that was recently fixed: "Non-negative number required" trying to read f# dll

Thanks for the replay, I will try it this evening. – Maxime Mangel Sep 19 '14 at 07:41
I still have the same error. I try to change Cecil downloaded from NuGet change the ones used by WebSharper. Nothing change... Just saw that Cecil on nugget date of 2012. Will try to find somewhere else. – Maxime Mangel Sep 19 '14 at 15:13
Really strange I build a project using the same NuGet than the last one and it's compile... – Maxime Mangel Sep 19 '14 at 21:04
