Either I’m having a problem understanding bin: deps, or something is not
working correctly with them.
I’ve tried the same thing on several different machines, and always seem to get
the same result.
Specifically, I’m trying to trim down unrequired dependencies on some of the
bootstrap ports to minimize headaches and heartburn maintaining them.
llvm-3.4 for example does not need any special perl.
In the portfile, it has
depends_run bin:perl:perl5 port:llvm_select
This means (to me) look for a binary named perl somewhere in the path, and
install perl5 if there isn’t one.
Of course, there always is a binary named “perl” in the path, so the depends
itself is a bit redundant, but at any rate, with all ports uninstalled, the
system perl is active:
$ port -v installed | grep active
$ which perl
/usr/bin/perl
$ printenv
PATH=/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
however, port still wants to install perl5 and all it’s supporting deps:
$ port info llvm-3.4
llvm-3.4 @3.4.2_12 (lang)
Sub-ports: clang-3.4
Variants: assertions, ocaml, universal
Description: The LLVM Core libraries provide a modern source- and
target-independent optimizer, along with code generation support for many
popular CPUs (as well as some less common ones!) These
libraries are built around a well specified code
representation known as the LLVM intermediate representation ("LLVM IR").

The following ports are dependencies of llvm-3.4 @3.4.2_12:
libffi
ncurses-bootstrap
zlib
xz-bootstrap
libiconv-bootstrap
gperf-bootstrap
gettext-bootstrap
perl5
perl5.28
xz
clang-3.4
cctools
libunwind-headers
llvm-3.4
llvm_select
python27-bootstrap
pkgconfig-bootstrap
bzip2
expat
openssl
clang_select
ld64
ld64-127
libmacho-headers
libiconv
gperf
libcxx
gettext
ncurses
db48
gdbm
readline
changing it to a path dependency doesn’t help:
depends_run path:bin/perl:perl5
$ port info llvm-3.4
llvm-3.4 @3.4.2_12 (lang)
...
Runtime Dependencies: perl5, llvm_select
Even sticking a symlink in ${prefix}/bin doesn’t work:
$ sudo ln -s /usr/bin/perl /opt/local/bin/perl
$ which perl
/opt/local/bin/perl
$ port info llvm-3.4
llvm-3.4 @3.4.2_12 (lang)
…
Runtime Dependencies: perl5, llvm_select
What stupid assumption am I making, or what am I doing wrong?
