 No. There is or was in port a "forget" argument…

 Yes, to know this would probably fine! (I am changing the Portfiles so
 that they do not show a new version.)


 The "broken pipe" comes from the right side of the pipe. `../meta/build-
 env` is a shell script (it sets and exports LD_LIBRARY_PATH), `guild`
 also. This one invokes the shell/scheme script
 `/opt/local/var/macports/build/_opt_local_var_macports_sources_lil.fr.rsync.macports.org_release_tarballs_ports_lang_guile/guile/work/guile-2.2.2/libguile/guile`,
 whch knows at the beginning LD_LIBRARY_PATH and then resets
 LD_LIBRARY_PATH, exports it invokes finally
 `/opt/local/var/macports/build/_opt_local_var_macports_sources_lil.fr.rsync.macports.org_release_tarballs_ports_lang_guile/guile/work/guile-2.2.2/libguile/.libs/guile`
 which probably cannot find its `/opt/local/lib/libguile-2.2.1.dylib` –
 through a cascade of internal shell script functions…

 I have no idea how to dive deeper…
