239The NetBSD build system requires a shell that supports modern POSIX
240features, as well as the "local" keyword in functions (which is a
241widely-implemented but non-standardised feature).
242
243Please re-run this script under a suitable shell.  For example:
244
245	/path/to/suitable/shell $0 ...
246
247The above command will usually enable build.sh to automatically set
248HOST_SH=/path/to/suitable/shell, but if that fails, then you may also
249need to explicitly set the HOST_SH environment variable, as follows:
250
251	HOST_SH=/path/to/suitable/shell
252	export HOST_SH
253	\${HOST_SH} $0 ...
254EOF
255    exit 1
256fi
