[gentoo-user] emerge --depclean - libcurl.la

emerge --depclean removed libcurl.la a few days ago.  I have a program that's not in world that uses it when built:  libtool complains that it's missing.  In /usr/lib64 there are libcurl .so files but no .la files.How can I get the libcurl.la library back and keep it so emerge --depclean doesn't remove it?Is there a way to protect files from emerge --depclean, kind of like the CONFIG_PROTECT variable, so it removes everything but what's protected?Thanks,dhk
