Additional context Problem is solved by installing libtool through the system package manager, but the port fails to check for this.

Also requires but fails to check for automake (for the aclocal) command - discovered this on OSX.

Please provide failure log /home/hamish/tmp/vcpkg/vcpkg-2021.04.30/buildtrees/libsass/autoconf-x64-linux-err.log.

Thanks.

Sorry I thought I had attached it to the original message. autoconf-x64-linux-err.log

src/GNUmakefile.am:27: error: Libtool library used but 'LIBTOOL' is undefined
src/GNUmakefile.am:27:   The usual way to define 'LIBTOOL' is to add 'LT_INIT'
src/GNUmakefile.am:27:   to 'configure.ac' and run 'aclocal' and 'autoconf' again.
src/GNUmakefile.am:27:   If 'LT_INIT' is in 'configure.ac', make sure
src/GNUmakefile.am:27:   its definition is in aclocal's search path.

Can you please try install libtool first? sudo apt-get install libtool.

[hmoffatt]

Yes it works if libtool is installed. If autoconf is missing you get a nice error, but not if libtool is missing.

The same problem occurs for automake (if aclocal is missing) on osx.

cc @Neumann-A, we should look for autoconf and libtool in advance in osx/linux I think.

[hmoffatt]

Same problem on Linux (Debian) - that is where I saw the libtool issue.

I can confirm this is still an issue on Ubuntu LTS 22.04, and is resolved by sudo apt install libtool -y (autoconf is needed as well)
