As promised, take a look:
   http://www.neuro.gatech.edu/users/cwilson/cygutils/testing/
The -src package contains ---  a patch, which does the following three 
things:

1) creates a ready-made Makefile.config to implement the "policy" I 
described:
   INSTALL_PREFIX = /usr/local (line 469)
     - you'll want to change that to /usr
   PNGHDR_DIR = /usr/include (line 466)
     - you'll want to make that /usr/include/libpngXX if
       you use libpng-1.0.13 or libpng-1.2.2
   LDSHLIB = -shared -Wl,--enable-auto-image-base  (line 460)
     - you'll wnat to change that to  -shared -Wl,--export-all
       since (1) auto-image-base is no longer recommended, and
       (2) export-all so you can take advantage of binutils' auto-export
       fucntionality
   INSTALLBINARIES = $(INSTALL_PREFIX)/bin/netpbm   (line 474)
     - this is the big controversy

2) creates a CYGWIN-PATCHES/netpbm.README files which describes how to 
build [merged|normal][shared|static], and some analysis I did about 
which version is the most space efficient.

3) creates CYGWIN-PATCHES/shtool :  netpbm is one of those packages that 
won't build outside of its own source tree, which complicates the 
script-driven build procedure.  As mentioned here: 
http://www.cygwin.com/setup.html, I used GNU shtool's 'mkshadow' 
function to replicate the whole source tree inside the .build directory 
via symlinks.

-src also contains: the build script, and the "pristine" tarball.  But, 
this is all based on 9.24, not 9.25, so it would take some adaptation to 
use it, and merge my stuff with yours -- if you want it.

Hope it's helpful.
