#46175: petsc @3.5.2_1 +complex build failure
------------------------------+--------------------------------
 Reporter:  johannes.feist@…  |      Owner:  macports-tickets@…
     Type:  defect            |     Status:  new
 Priority:  Normal            |  Milestone:
Component:  ports             |    Version:  2.3.3
 Keywords:                    |       Port:  petsc
------------------------------+--------------------------------
 The PETSc port by default enables hwloc support (configuring with "--with-
 hwloc"). However, this is incompatible with support for complex numbers
 (enabled by +complex), with the following error message from the PETSc
 configure script:
 {{{
 :info:configure
 *******************************************************************************
 :info:configure          UNABLE to CONFIGURE with GIVEN OPTIONS    (see
 configure.log for details):
 :info:configure
 -------------------------------------------------------------------------------
 :info:configure Cannot use hwloc with complex numbers it is not coded for
 this capability
 :info:configure
 *******************************************************************************
 }}}

 The attached patch fixes this by moving support for hwloc into a variant
 +hwloc that is enabled by default, but conflicts with +complex.
