I just wanted to follow up on this readDCF issue with install.packages
on AIX on R 3.*. I'm happy to help try potential solutions or debug
if anyone could point me in the right direction.
To re-cap, it appears readDCF is segfault'ing since R 3.* on AIX.
This was not the case up until R 2.15.3. This makes install.packages
not usable. Thanks.
