It appears that you skipped over one operation that the install procedure told you to do.  In the area 31DEC20/MACINT/ there is a file fix_aips_elcap.sh.Execute this file under bash.  You will need sudo privilege.  There is also a file called sysctl.conf which must be in /etc to raise the size of the allowed shared memory. instructions below
On the latest "leopard", "snow leopard", "lion", "mountain lion", and "yosemite" (X 10.5-10.10) systems, /etc/rc is gone and creating it will have no effect. You need to create an /etc/sysctl.conf file and put the values in it,
kern.sysv.shmmax=10485760kern.sysv.shmmin=1kern.sysv.shmmni=32kern.sysv.shmseg=8kern.sysv.shmall=4096You should use the values you had when you were running tiger. Those could be in /Previous\ System/etc/rc, assuming you have "Previous System". So three different OS upgrades and three different ways to adjust the default shared memory. Note: You will need to reboot the system for the change in shared memory to take place. You can check if the shared memory changes happened by typing "sysctl kern.sysv" in a terminal or xterm window. Look for the kern.sysv.shm* values. If the values have not changed, make sure you haven't inadvertently left in "sysctl -w" in the /etc/sysctl.conf file or mis-typed one of the values. If the /etc/sysctl.conf file is not properly formatted, or shmmax is not an integer multiple of shmall, the shared memory will not be adjusted after the reboot.
