Machine:                MacBook Pro, 15"
                        MacBookPro10,1
Processor Name:         Intel Core i7
Number of Processors:   1
Total Number of Cores:  4
OS Version:             10.8.5
Xcode verson:           5.1
MacPorts version:       2.4.1

There is a fix at least for the above machine: one should cause the
build system to use 'macports-gcc-6' instead of the default compiler.
One way to do so (maybe not the best) is do replace the original
Portfile line

compiler.blacklist  {gcc-4.0 < 5493}

with the lines

compiler.blacklist  {gcc-4.0 < 5493}

compiler.whitelist  macports-gcc-6

poppler: use the cxx11 1.1 PortGroup

Poppler now requires C++11 and is broken on libstdc++ systems
without the cxx11 PortGroup hack.

See: #54249

For the error: unrecognized command line option "-std=c++11" issue see #54282

Replying to mojca:

The additional statement somewhere at the beginning og poppler's Portfile (port file poppler) is:

PortGroup      cxx11  1.1
