make sure env variable D is unset before building

[jester@…]

I ran into an old problem again building ipp-2.5: the ltmain.sh used at least in building psphot checks a global environment variable D. If that is set by the user, building fails with weird errors where libtool looks for a library in the wrong directory.

psbuild should make sure that no environment variable D is set.

Also, I think I needed to unset F77 and F2C which were set by default for the iraf installation in our system, but led to the wrong f77 compiler being found by psbuild.

The libtool version checking the D env variable seems to be an inofficial one created by gentoo, so maybe that's actually a bug rather than an enhancement request.

In any case, it would be nice if D, F77 and F2C were all unset by psbuild.

How to unset environment variable D ?
I met same problem in building psphot.
The error messages I have are

Just say

unset D

etc. at the command line.

I unset D, F77 and F2C
I still have same error messages.
Did I need to unset other environment variable?

this is now done automatically by psbuild.
