ocaml-safepass needs the crypt-blowfish patch that is not include in the mainline glibc. So the following line should be added to DEPEND: sys-libs/glibc[!vanilla]
I'm contacting the author for more informations. So, this bug can wait.
i may have searched wrongly but i see nothing about blowfish in our glibc patchset. ccing glibc maintainers, they may have some comments.
No, it's not a bug, I'm sorry. It was a bug on in crypt_blowfish and I made a wrong conclusion. The author is trying to fix that.
