New description:

 port install groff hangs during configuration. Manually running configure
 from the build directory works.

 Tried various combinations of port clean groff etc but nothing helped.

 It turns out that a call to pnmtops hangs.

 What did help was to change configure (in
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_sysutils_groff/groff\
 /work/groff-1.22.2/):

 # original line:
 {{{
    if echo P2 2 2 255 0 1 2 0 | pnmtops -nosetpage > /dev/null 2>&1 ; then
 }}}

 # changed line
 {{{
    if echo P2 2 2 255 0 1 2 0 | $pnmtops -nosetpage > /dev/null 2>&1 ;
 then
 }}}

 Note that the configure file spends some effort to figure out the path to
 pnmtops (putting it in the variable with the same name) so regardless of
 the hanging issue the code that uses plain 'pnmtops' instead of '$pnmtops'
 looks suspicious. There are code a few lines down that sets
 pnmtops_nosetpage to a value that also ignores the path found for pnmtops
 but I did not change those.

 I have no idea why using a full path makes a difference here. It is even
 possible that I misunderstood the configure script and that the if-test
 just quietly fails after my change, but the hang disappeared.
