Hello,

should the final patch-shebangs phase not include the generated output
path (well, the bin subdirectory) in its $PATH?

In texlive I see lines such as
patch-shebang: ./texmf-dist/tex/luatex/lualibs/lualibs-compat.lua: warning: no binary for interpreter `texlua' found in $PATH

The file starts with 
#!/usr/bin/env texlua
and texlua is a binary created in the texlive output (actually, bin/texlua is
a symbolic link to the elf binary bin/luatex).

Andreas

It already does.

(And the mention of $PATH in this message is misleading.)

Could it be that the symlink doesn’t exist yet at the time the
‘patch-shebangs’ phase runs?

HTH,
Ludo’.

Hm.

I think it already exists; the only thing between patch-shebangs and strip is
             (setenv "PATH" (string-append (getenv "PATH") ":" out "/bin"))
             (system* "updmap-sys" "--nohash" "--syncwithtrees")
             (system* "mktexlsr")
             (system* "fmtutil-sys" "--all")))
