Hum. I am not able to reproduce.

First, let be sure nothing is already in the store.

--8<---------------cut here---------------start------------->8---
$ guix gc --list-dead | grep x265-3.5-static
finding garbage collector roots...
determining live/dead paths...

$ guix gc --list-live | grep x265-3.5-static
finding garbage collector roots...
determining live/dead paths...

$ find /gnu/store -maxdepth 1 -type d -name "x256-3.5-static" -print
--8<---------------cut here---------------end--------------->8---

Second, try to install:

--8<---------------cut here---------------start------------->8---
$ guix install x265 --dry-run
guix install: warning: Your Guix installation is 92 days old.
guix install: warning: Consider running 'guix pull' followed by
'guix package -u' to get up-to-date packages and security updates.

The following package would be installed:
   x265 3.5
--8<---------------cut here---------------end--------------->8---

And ’static’ output does not seem required.

Could you give your Guix revision?  Mine is 056910e; please note x265
had not be modified since a while and the package isn’t grafted.

--8<---------------cut here---------------start------------->8---
$ guix build x265 -d
/gnu/store/5v0d3wf3rhy69i1fl0jdchpmwy5wxbas-x265-3.5.drv

$ guix build x265 -d --no-grafts
/gnu/store/5v0d3wf3rhy69i1fl0jdchpmwy5wxbas-x265-3.5.drv
--8<---------------cut here---------------end--------------->8---

Hum, I don’t know where could the observed behaviour come from?

Cheers,
