Can we assume that a dependency on gnutar will provide either
${prefix}/bin/gnutar or ${prefix}/bin/tar?
To check for gnutar or tar, maybe the following could be used:
if [file exists ${prefix}/bin/gnutar] {
set gnutar ${prefix}/bin/gnutar
} elseif [file exists ${prefix}/bin/tar] {
set gnutar ${prefix}/bin/tar
}
# maybe some kind of confirmation that we get gnutar?
# exec $gnutar --version
To set this variable globally for a Portfile, where is the best place to put
it? Assume the dependency on gnutar requires an installation.
TIA,
Darren
