trouble compiling harfbuzz: env does not find meson

[xolodho <xolodho%gmail.com@localhost>]

Hi!

I'm having trouble to get the `harfbuzz` package to compile in pkgsrc
(as non-root user), it fails when attempting to run meson, more
precisely `env` fails to find `meson` even though the binary is at
`/usr/pkg/bin/meson` (from package `meson-0.60.1`). Actually if I run
`env meson` in the shell it prints `env: meson: No such file or
directory`, and basically that's the error I get when running `make` on
`/usr/pkgsrc/fonts/harfbuzz`. `/usr/pkg/bin` is listed in the PATH
variable of the user's shell, and meson can be found and run normally
when invoked by name.

What am I missing here ? Maybe something misconfigured?
any pointers are much appreciated!

running NetBSD 9.2 i686.
