gtk+ 2.2.4 install: configure can't find image libraries

[Micah Abbott <micah abbott sun com>]

Hi all-

I'm trying to install gtk+ v2.2.4 on my Solaris 9 system, but the 
configure script is missing all of my image libraries:


checking whether to build gmodulized gdk-pixbuf... yes
checking whether dynamic modules work... yes
checking for TIFFReadScanline in -ltiff... no
checking for TIFFWriteScanline in -ltiff... no
checking for TIFFFlushData in -ltiff34... no
configure: WARNING: *** TIFF plug-in will not be built (TIFF library not 
found) ***
configure: error:
*** Checks for TIFF loader failed. You can build without it by passing
*** --without-libtiff to configure but some programs using GTK+ may
*** not work properly


I disabled libtiff and tried again.  This time it was libjpeg that could 
not be found.  I disabled both libtiff and libjpeg, but now libpng 
couldn't be found.

I searched the archives and found a suggestion of passing in 
CPPFLAGS=-I/usr/local/include and CFLAGS="-g -I/usr/local/include" to 
configure, but that did not help my problem.

I am positive that installed the TIFF, JPEG, and PNG libraries.  And I'm 
pretty sure that it was done correctly.

Any suggestions?

Thanks in advance.
