I don't understand.

All four variants below fail in exactly the same way:

#+begin_src sh
  jpm --cc=gcc -l install sh
#+end_src

#+begin_src sh
  jpm --cc=/home/user/.guix-profile/bin/gcc -l install sh
#+end_src

#+begin_src sh
  jpm --cc=/gnu/store/x2kv3zw2k7ql211m5kvb6yw401gab0x9-gcc-toolchain-14.2.0/bin/gcc -l install sh
#+end_src

#+begin_src sh
  jpm --cc=/gnu/store/lq9y7sd4mvffs4hqp3hkr9fnd384pnkj-gcc-14.2.0/bin/gcc -l install sh
#+end_src

Note that the last variant uses an absolute path.

Either I'm not using the "--cc" option correctly.  Or for some
dependency of "sh" (specifically, posix-spawn) the compiler has been
hardcoded to "cc" and it's not picking up the option being passed to
jpm.

Further, if the above work for you in a "--pure" guix shell (where it
doesn't for me), that's surprising.

It is _only_ when I provide a fake "cc" (which is simply a symlink to
gcc) that things work.
