please add | keepdir /var/spool/capisuite/{done,failed,sendq,users} to src_install. sys-devel/patch can be dropped - it's in eutils. virtual/libc should be added and i'm not sure about sys-devel/gcc. media-sound/sox, media-libs/tiff, virtual/ghostscript are only needed at runtime. DEPEND="dev-lang/python sys-devel/gcc virtual/libc net-dialup/capi4k-utils" RDEPEND="${DEPEND} media-sound/sox media-libs/tiff virtual/ghostscript" Then it depends on sfftobmp which is not in the tree ATM (bug #53889). For full functionality (using MailAndSave) a virtual/mta (called by "sendmail -t -f") is needed too.
And media-gfx/jpeg2ps should be added to runtime-deps -- it is also called in /usr/lib/python*/site-packages/cs_helpers.py This is what the manual says: "The jpeg2ps command is used to convert color fax files to the PostScript format for mail delivery. It's not so important, unless you want to be able to receive color faxes. Unfortunately, there's currently no way to disable the reception of color faxes with AVM cards due to a bug in the AVM CAPI driver. So if someone sends you a color fax (which seems to be a very rare case), you'll need this package - unless you'll get a mail stating this error." #69546 should be fixes too. (If it helps: Debian does the same in <http://ftp.debian.org/debian/pool/main/c/capisuite/capisuite_0.4.4-7.diff.gz>)
I think sys-devel/gcc is not necessary. Waiting for bug #53889; in the mean time capisuite-0.4.4-r1 is out there.
Add media-gfx/sfftobmp to RDEPEND.
