If the full output that you provided the link for [1], I noticed the  
following line just after the first instance of the text I've quoted  
above:

Error: Target com.apple.build returned: shell command " cd "/opt/ 
local/var/db/dports/build/ 
_opt_local_var_db_dports_sources_rsync.rsync.macports.org_dpupdate_dport 
s_lang_gcc42/work/build" && make bootstrap -j 2 " returned error 2

It seems that you've set the -j flag somewhere to try to speed up  
make by getting it to do two operations in parallel, but  
unfortunately that's known to break builds if the Makefiles don't  
quite specify the dependencies correctly.  Try removing the -j flag  
from wherever you've set it and see if that helps.

Kind regards,
