Hi there, 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.
