When installing ntfs3g it has a build time dependency on libgcrypt that isn't pulled in. it dies with this output: checking for LIBGCRYPT - version >= 1.2.2... no configure: error: ntfsprogs crypto code requires the gcrypt library. The only way to install it is: USE="-crypt" emerge -av ntfs3g or emerge libgcrypt before ntfs3g if you have the "crypt" flag set. Reproducible: Always Steps to Reproduce: 1. uninstall libgcrypt and ntfs3g if they are installed. 2. emerge ntfs3g on its own 3. watch output for error on libgcrypt not being there.
oups. thanks for reporting & fixed in portage.
