Hi,
For those who is installing pg 7.4.8 srpms on FC4, there seems to be a problem on compile. There is a small bug on srpms 7.4.8 in particular
postgresql-7.4-plperl.patch
There is an extra comma after the CFLAGS. I have contacted Lamar, not sure if he maintains it currently. Hope this helps someone and its not a duplicate post.
