Comment (by mmoll@…):

 It looks like you are compiling SLEPc yourself rather than installing it
 through MacPorts. I cannot reproduce your error with `port install slepc`
 on OS X 10.10.3:
 {{{
 > port installed arpack slepc openmpi-default
 The following ports are currently installed:
   arpack @3.1.5_0+accelerate+gcc49 (active)
   openmpi-default @1.7.5_3+gcc49 (active)
   slepc @3.5.3_1+openmpi (active)
 }}}
