I tried installing on linux and: 

make[2]: Leaving directory `/mnt/usb1/scratch/wstein/build/sage-4.4.3.rc0/spkg/build/libpng-1.2.35.p2/src'
make[1]: Leaving directory `/mnt/usb1/scratch/wstein/build/sage-4.4.3.rc0/spkg/build/libpng-1.2.35.p2/src'
./spkg-install: line 55: syntax error near unexpected token `fi'

It doesn't work yet on Cygwin itself (on a clean install): 

make[2]: Leaving directory `/home/wstein/sage-4.4.3/spkg/build/libpng-1.2.35.p2/src'
cp: cannot stat `/home/wstein/sage-4.4.3/local/bin/cygpng12-0.dll': No such file or directory

The above failure report is on cygwin upgraded to the latest version as of june 4, 2010.

The build completes successfully once "file" is installed in winxp3. If "file" is not installed, then Cygwin has a difficult time making shared libraries. This is why this wasn't an issue initially with my sage-4.3.5 install in winxp2.

We need to make "file" a preqreq.

Yes, winxp3 is missing a lot of prerequisites. MPIR also fails to build there.
