forgot to add - i have installed libpng-1.5.7
Looks like a late fallout of the libpng15 upgrade. Actually, you should have a news item ("eselect news list") for this. Just read the 2011-10-15-libpng15 item and follow its instructions.
wieneke ~ # eselect news read 8 2011-10-15-libpng15 Title Upgrade to libpng15 Author Samuli Suominen <ssuominen@gentoo.org> Posted 2011-10-15 Revision 1 After upgrading from libpng14 to libpng15 it's important that you rebuild cairo and gdk-pixbuf as soon as possible if they are installed. Then you can proceed with rebuilding the rest of the software against the new library: # revdep-rebuild --library libpng14.so.14 -- --keep-going Note: It might be necessary to run the previous command more than once. If you find packages not building with the message "ld: cannot find -lpng14", they are likely caused by broken libtool archives (.la) in your system. You can identify those files with following one-liner: # find /usr/ -name '*.la' -exec grep png14 {} + Once you have identified the broken files, you can either delete them, edit them in place and replace png14 with png15, or re-emerge the packages they belong to.
