The following photo is a lightened version of the important portion
of the above jpg. It was lightened to be sure the difference in
lighting due to time of day was not the cause of the apparent
difference in the size of the subject blobs.

Something else that is inconsistent with condensing ice forming on
the location in question is that such ice typically forms in a
clearly crystalline form, a kind of hoar frost. The white stuff on
the strut looks smooth and globular. It might be said that the stuff
is melting, but then that is inconsistent with the fact the
underlying and nearby globs have remained in place for 84 days, and
also appear to have accumulated a dust covering.

It appears that the globular drops are on another strut or two also. (The strut in the foreground appears to have a few blobs.)
The photo: Sol 73, 13:02:13 camera elevation -25 deg, azimuth 150: http://phoenix.lpl.arizona.edu/images.php?gID=19371&cID=209 http://phoenix.lpl.arizona.edu/images/gallery/lg_19371.jpgAgain, it pays to flip the above photo 180 degrees because it is upside down.
For comparison, here again are the photos compared prior regarding the large increasing set of blobs:

I still think this may indicate leaks or spills from the chemical analysis areas. It will be interesting to keep an eye out for further growth though.

Carefully registering and toggling these two photos shows apparent motion of some of the globs on the thicker part of the strut.
