Emerge php fails

I have a problem when trying to emerge php. It says that no usable png libaray is found, however I emerged libpng. Here's the exact error:

checking for png_create_read_struct in -lpng... no
configure: error: No usable pnglib library found.

!!! ERROR: The ebuild did not complete successfully.
!!! Function econf, Line 10, Exitcode 1
!!! econf failed

Any suggestions would be appreciated.

You could also try running ldconfig before emerge. I've noticed that occasionally (rarely) the library bindings don't get properly updated after some packages.

Hope this helps!

Got the same error and checked updating pdflib or something. Checked config.log and saw some familiar undefined symbols. Somehow the ld command (configure script) doesn't include -lm -lz for the libpng package, although it is in /usr/lib/pkgconfig/libpng12.pk. So I don't think these packages use the pkgconfig system.

So use the following:
