brew install libpng

...ok.(but this libpng library already has been installed on My Mac)

IM_INCPATH=/usr/X11/include IM_LIBPATH=/usr/X11/lib perl Makefile.PL

indicate include path and library path,and do 'perl Makefile.PL'

but,below is result

Libraries found:

FT2
JPEG

Libraries not found:

GIF

PNG: v1.5: includes found - libraries found
PNG: Test code failed: Can't link/include 'png15'

Can't link/include 'png15' ???? I can't resolve this problem by myself. please give me your support.

Answer 1

The paths are wrong. Homebrew installs to /usr/local/Cellar.
