#45003: Cannot install control package in Octave 3.8.1 on Mac OSX
----------------------------+------------------------------------
 Reporter:  MacPorts@…      |      Owner:  macports-tickets@…
     Type:  defect          |     Status:  new
 Priority:  Normal          |  Milestone:
Component:  ports           |    Version:  2.3.1
 Keywords:  octave control  |       Port:  octave, octave-control
----------------------------+------------------------------------
 After MacPorts upgraded octave to 3.8.1, octave could no longer load the
 .oct files that came with the control package. (There was no path problem,
 but dlopen() failed anyway, with "Reason: image not found", but the binary
 file was there, dated April 18, meaning it's the same one that used to
 work.)   I uninstalled octave* and rebuilt like this (as I usually do):

 I originally reported this to the GNU Octave bugtracker, and got this
 reply:
 ...
 "With either Octave 3.8.1 and 3.8.2 compiled manually on Mavericks I
 cannot reproduce your problem so this appears to be a MacPorts rather than
 an Octave problem:"
 {{{
 >> pkg install -forge control
 For information about changes from previous versions of the control
 package, run 'news control'.
 >> tf (1)

 >> version
 ans = 3.8.1
 }}}
 "... If I have to guess, though, a possible cause could be mixing clang
 and gfortran which, according to my experience, never worked properly on
 OSX.   When building OSX binaries I use gcc for Octave and ALL its
 dependencies. In MacPorts you can do that by specifying the  gccXX variant
 when available or specifying the compiler explicitly."
