  I've pushed a fix.

  Is it in the directories which are printed out above?

  What does the "config.log" file say?  i.e.
src/modules/rlm_eap/types/rlm_eap_pwd/config.log  It should be filled
with logs from all of the attempts to compile the source.

  The same comments apply as above.

  The same comments apply here, too.
