次のスクリプトを考えてみましょう。
#!/usr/bin/env bash
set -ex
wget -N http://archive.ubuntu.com/ubuntu/pool/universe/o/ocaml-re/ocaml-re_1.7.3-2.dsc
wget -N http://archive.ubuntu.com/ubuntu/pool/universe/o/ocaml-re/ocaml-re_1.7.3.orig.tar.gz
wget -N http://archive.ubuntu.com/ubuntu/pool/universe/o/ocaml-re/ocaml-re_1.7.3-2.debian.tar.xz
dpkg-source -x ocaml-re_1.7.3-2.dsc
cd ocaml-re-1.7.3
dpkg-buildpackage -rfakeroot -d -us -uc -S || exit $?
debuild -S || exit $?
実行してみるとわかりますが

私が混乱しているのは、jbuilderを（opam経由で）インストールしましたが、正しくdebuild -S実行され成功したようですが、見つからないことです。dpkg-buildpackage -rfakeroot -d -us -uc -Sここで何が起こっているのでしょうか？

私が見つけたマニュアルページを読んだ後環境変数について、内容は次のとおりです。
環境変数はパッケージのビルドに影響を与える可能性があるため、デビルドはしばしば
TERM、HOME、LOGNAME、GNUPGHOME、PGPPATH、GPG_AGENT_INFO、 、FAKEROOTKEY、DEB_*、 (C、CPP、 、CXX) 変数とその変数を除くすべての環境変数とロケール変数と環境を削除して誤って整理します。 。未設定の場合に設定され、未設定の場合に設定されます。LDFFLAGS_APPENDLANGLC_*TERMdumbPATH"/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11"[...]
削除されたPATHの先頭にディレクトリを追加するオプションがあります
--prepend-path。これはccache、同じツールを使用してdistccビルドしたい場合に便利です。
したがって、問題はopamバイナリが存在するため、PATHここで見つけることができないということです。
