I have a problem with perl scripts that attempt to load cygpixman-1-0.dll. When 
running a test on PerlMagick-6.76 I get the following:

$ make test

Sometimes, see example t/filter.t, it takes one failed attempt, in the other 
example, t/montage.t, it takes many attempts. Eventually, cygpixman-1-0.dll gets 
loaded, I gather, because the test succeeds. I noticed the same problem with 
other perl scripts, e.g., the ones in LaTeXML.

What causes this problem. What package does cygpixman-1-0.dll belong to? Perhaps 
I need to reinstall it?
