A few last versions of libwebkitgtk4 fail to build on mipsel. It turns out that upstream assumes that MIPS systems use 4k pages, which is not true for any ALT-based MIPS system -- we use 16k pages. The following change fixes the build: http://git.altlinux.org/people/iv/packages/?p=libwebkitgtk4.git;a=commitdiff;h=refs/heads/mips-16k-pages Please include this or similar change into the next build of libwebkitgtk4.
