Actually you want to put the reinplace in a post-patch phase like this
post-patch {
reinplace "s|@FINKPREFIX@|${prefix}|g" ${worksrcpath}/patched_file
}
This way the file in question will be patched to include the place
holder and
then the place holder will be replaced with the appropriate substitution
after
all patches have been completed.
