[FFmpeg-user] OSX lion, trying to compile from git fails

Actually I'am packing this next to some bash powered droplet, so i
assume that 12 core cpu could behave differently than my home quad
core? (hence --enable-runtime-cpudetect). Dunno if this is OS related
as well? Like Lion vs Snow leopard?.

The compilation I do is in RAM disk, so "make install" will copy a
binary to a predefined folder only (i think?)

The RAM disk is defined as:

DISK_ID=$(hdid -nomount ram://26214400) && newfs_hfs -v tempdisk
${DISK_ID} && diskutil mount ${DISK_ID} &&
SOURCE="/Volumes/tempdisk/sw" && COMPILED="/Volumes/tempdisk/compile"
&& mkdir ${SOURCE} && mkdir ${COMPILED} && export

Thanks for all the suggestions, iam really glad this worked out.
