I rebuilt aspell, but gramps still core dumps. The backtrace shows the same as 
previously. :/

These appear to be the same, but its possible my blurry eyes may be 
overlooking something obvious.

I initially tried to upgrade all ports using 'portupgrade -fa', which ran for 
days and left me with 11 ports failed and about 300 skipped as a result. I 
managed to upgrade the failed ones with 'make install' then 'portupgrade -fa' 
again, rather than trying to upgrade the skipped 300 one at a time. When this 
ran into the same series of failures as before I realized the error and 
simply removed all ports 'pkg_delete -f \*' and reinstalled them 
using 'pkg_add -r'. I am currently in the process of 'portupgrade -aR' 
following a recent portsnap which shows a small handful of packages needing 
upgrades.
