Ahhh.  Sorry. :-)

Yes, but there are other concerns.

You can do

   ./configure LIBS=-lpng14

if the library would be matched like libpng14.so.  However, you would 
also need the headers to match that library and you will have libpng 
1.5 headers installed.  This means that you would also need to install 
the libpng 1.4 headers.  If they are installed, you could tell 
configure to use them by also adding something like.

   CPPFLAGS=-I/the/path/libpng-1.4

Are you able to (and willing to) substitute the development/snapshot 
version of the library instead?
