Comment (by barracuda156):

 Replying to [comment:1 jmroot]:
 > Not a base bug. The eigen3 Portfile sets `compiler.cxx_standard   2011`
 which is what causes it to depend on a C++11 capable compiler.

 I do not get the same error with every C++11 port. This only happens when
 `noarch` is there.
 Say:
 {{{
 10:~ svacchanda$ port deps libptytty
 Full Name: libptytty @2.0_0
 Build Dependencies:   cmake, gcc12
 Library Dependencies: libgcc

 10:~ svacchanda$ port deps libsigcxx2
 Full Name: libsigcxx2 @2.10.8_0
 Extract Dependencies: xz
 Build Dependencies:   pkgconfig, mm-common, m4, graphviz, doxygen,
 libxslt,
                       gcc12, meson, ninja
 Library Dependencies: libgcc
 }}}

 But:
 {{{
 10:~ svacchanda$ port deps eigen3
 Full Name: eigen3 @3.4.0_1
 Extract Dependencies: lbzip2
 Build Dependencies:   cmake, pkgconfig, clang-11
 Library Dependencies: libgcc

 10:~ svacchanda$ port deps eigen3-devel
 Full Name: eigen3-devel @3.4-tracking-20221231_0
 Extract Dependencies: lbzip2

 Library Dependencies: libgcc

 10:~ svacchanda$ port deps nanoflann

 Build Dependencies:   cmake, clang-11
 Library Dependencies: libgcc
 }}}
