The package perl-mime-tools in [Extra] was required by the amavisd-new.While starting amavisd,the error below has occured.

fetch_modules: error loading optional module MIME/Decoder/BinHex.pm: Can't locate Convert/BinHex.pm in @INC (@INC contains: /usr/lib/perl5/site_perl/5.10.1 /usr/share/perl5/site_perl/5.10.1 /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5/core_perl /usr/share/perl5/core_perl /usr/lib/perl5/current/x86_64-linux-thread-multi /usr/lib/perl5/current /usr/lib/perl5/site_perl/current/x86_64-linux-thread-multi /usr/lib/perl5/site_perl/current) at /usr/share/perl5/vendor_perl/MIME/Decoder/BinHex.pm line 43. BEGIN failed--compilation aborted at /usr/share/perl5/vendor_perl/MIME/Decoder/BinHex.pm line 43. Compilation failed in require at /usr/sbin/amavisd line 197.

And then,i check the code of /usr/share/perl5/vendor_perl/MIME/Decoder/BinHex.pm on line 43,the following code indicate that perl module Convert BinHex is needed.

use Convert::BinHex;

I also checked the same debian package in http://packages.debian.org/en/sid/libmime-tools-perl,and the perl-convert-binhex was absolutely the dependency. Now,the perl-convert-binhex is in AUR,so please fix the PKGBUILD of perl-mime-tools and move perl-convert-binhex into offical repo. I have fill out a bug about this in FS#23144,hope someone can solve this problem.
