#62695: jekyll @0.30a_4 rebuilding failure
----------------------+--------------------
 Reporter:  ippoliti  |      Owner:  (none)
     Type:  defect    |     Status:  new
 Priority:  Normal    |  Milestone:
Component:  ports     |    Version:  2.6.4
 Keywords:            |       Port:  jekyll
----------------------+--------------------
 After updating all the outdated ports, I installed jekyll on my machine
 equipped with MacOS 10.13.6 (Xcode 10.1 (10B61)). No installation problems
 at that time but when I tried to run jekyll I got the error message:

 the file '/opt/local/bin/jekyll' has not the right magic number: expected
 Caml1999X029, got Caml1999X025

 like if I got a binary of the port built for an older version of ocaml.
 Then, I tried to rebuild the port and I got the following error message:
 {{{
