I just installed postgres 7.0.2 on a Red Hat 6.2 system, from the RPM
files. The installation created a /usr/include/pgsql/os.h symlink, which
points to ".././include/port/linux.h". This is a broken link. I found a
"port" directory nearby, but it contains a single empty directory, and no
header files. How can I correct this symlink?
