Possible bug in prt-get

Hi, I found a strange behaviour in prt-get, I suppose this might be a bug. In my Pkgfile I have: [...] TIP=`cd $REPO && hg tip | grep changeset | cut -d ':' -f2 | sed -e 's/ //g'` version=rev-${TIP} [...] prt-get builds the package properly: =======> Building '/home/pkgmk/packages/uki-awesome#rev-6738-1.pkg.tar.gz' succeeded. but than when it tries to install it: prt-get: installing uki-awesome rev-${TIP}-1 pkgadd: could not open uki-awesome#rev--1.pkg.tar.gz: No such file or directory Is this a bug? And if not - how can I fix my Pkgfile? Cheers, -- Łukasz Gruner
