The issue here is that the %current-target-system and %current-system
are not defined at build time. You need to force their evaluation by
using "unquote", this way:
--8<---------------cut here---------------start------------->8---
(arguments
`(#:phases
...
(if (string-prefix? "powerpc64le"
,(or (%current-target-system)
(%current-system)))
...)))
--8<---------------cut here---------------end--------------->8---
>
> + #~(let-system (system target)
> + ;; LuaJIT is not ported to powerpc64le* yet.
Here also you need to unquote this part, using "ungexp":
--8<---------------cut here---------------start------------->8---
#$(let-system (system target)
...
--8<---------------cut here---------------end--------------->8---
Thanks,
Mathieu
