FYI install that means from your ${P}.cygport directory:

$ tar -xf ${P}-${V}-{R}.${ARCH}/dist/${P}/${P}-${V}-{R}.tar.xz -C /
$ tar -xf
${P}-${V}-{R}.${ARCH}/dist/${P}/${P}-debuginfo/${P}-debuginfo-${V}-{R}.tar.xz -C /

as the quick and dirty way to get most packages you just built into your local
Cygwin setup, without the formality of postinstall rebasing etc. which is likely
advisable in all Cygwin 32 setups.
