[daip] Problem in AIPS in Mac

[pc8s at virginia.edu]

Hi,

I am running Mac OS X 10.5.7 on my mac laptop. I have been using AIPS on
it for past 6 months and everything seems to be running fine until 2 days
back. However, since today morning I am not able to run AIPS. The error it
gives is the following:
user156-101:~ poonam$ . /Users/poonam/AIPS/LOGIN.SH
user156-101:~ poonam$ aips tv=local
-bash: aips: command not found

I just don't know what is wrong. Everything seems right to me. Can you
tell me what is the problem?

Thanks
Poonam
