 mesa install fails on a non-root installation of MacPorts:

 {{{
 $ port install mesa
 --->  Fetching mesa

 Error: Target org.macports.destroot returned: xinstall: chown/chgrp
 /mp/var/macports/build/_Users_rschmidt_macports_dports_x11_mesa/work/destroot//mp/bin/glxgears,
 Operation not permitted
 Error: Status 1 encountered during processing.
 }}}

 The problem lines in the portfile are these:

 {{{
         post-destroot {
                 xinstall -o root -m 755 -d "${destroot}${prefix}/bin"
                 xinstall -o root -m 755
 "${worksrcpath}/progs/xdemos/glxgears" "${destroot}/${prefix}/bin"
                 xinstall -o root -m 755
 "${worksrcpath}/progs/xdemos/glxinfo" "${destroot}/${prefix}/bin"
         }
 }}}

 They were added in r47380. A proposed fix is attached.
