Comment(by anotherperson2011@…):

 Similar errors with 2.8.7, though this time cmExprParser.cxx.o is not
 being created due to the same missing symbols.

 The issue appears to be with lines in 'cm*.cxx' that state :

 {{{
 #include <elf.h>
 }}}

 'elf.h' does not appear to be part of the cmake distribution.
 I have 55 versions of elf.h on my machine, in various source
 distributions, but the above code finds the only one in the common system
 paths at /usr/include/elf.h,
 which on this Mac system is a one line file consisting of:

 {{{
 #define CONFIG_BINFMT_ELF 1
 }}}

 Hence the build issue.
 Perhaps you could include 'elf.h' in the cmake build, or explicitly point
 to one elsewhere within MacPorts so that the expected one is used?
