 Hello,

 When using gmsh @4.11.1_5+mpich+openblas+python310 on OSX 14.4.1 (Xcode
 15.4 Build version 15F31d), the python bindings complain about mssing
 OpenCASCADE.  However, I do have opencascade @7.8.0_0 installed (as
 required by the Portfile).

 Here is a minimal Python script for reproducing:
 {{{
 import gmsh
 gmsh.initialize()
 model = gmsh.model()
 tags = model.occ.addBox(0, 0, 0, 1, 1, 1)
 }}}

 On my system it gives the following:
 {{{
 Error   : Gmsh requires OpenCASCADE to add box
 ---------------------------------------------------------------------------

       2 gmsh.initialize()

       4 model = gmsh.model()

    7453                 byref(ierr))
    7454             if ierr.value != 0:

    7456             return api_result_

 Thank you for the attention.
