There is a bug in pvm-3.4.5-r2.ebuild which causes improper installation. Programs get installed into /usr/share/pvm3/lib/LINUX64, but symbolic links get created in /usr/bin that point to /usr/share/pvm3/lib/LINUX. emerge --info: Portage 2.0.51.22-r3 (default-linux/amd64/2005.0, gcc-3.4.4, glibc-2.3.5-r2, 2.6.12-gentoo-r10 x86_64) ================================================================= System uname: 2.6.12-gentoo-r10 x86_64 Dual Core AMD Opteron(tm) Processor 275 Gentoo Base System version 1.6.13 dev-lang/python: 2.3.5, 2.4.2 dev-util/ccache: [Not Present] dev-util/confcache: [Not Present] sys-apps/sandbox: 1.2.12 sys-devel/autoconf: 2.13, 2.59-r6 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.15.92.0.2-r10 sys-devel/libtool: 1.5.20 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="amd64" AUTOCLEAN="yes" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=athlon64 -O2 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/2/share/config /usr/kde/3/share/config /usr/lib/X11/xkb /usr/lib64/mozilla/defaults/pref /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/X11/app-defaults /etc/bonobo-activation /etc/dev.d /etc/devfs.d /etc/esd /etc/eselect /etc/eselect/compiler /etc/fonts /etc/foomatic /etc/gconf /etc/gnome-vfs-2.0 /etc/gtk /etc/gtk-2.0 /etc/hal /etc/imlib /etc/init.d /etc/openoffice /etc/pango /etc/ppp /etc/sgml /etc/sound /etc/ssl /etc/terminfo /etc/udev /etc/vga /etc/wget /etc/xdg /etc/xml /etc/env.d" CXXFLAGS="-march=athlon64 -O2 -pipe" DISTDIR="/common/portage/distfiles" FEATURES="autoconfig distlocks sandbox sfperms strict userpriv usersandbox" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/Linux/distributions/gentoo" MAKEOPTS="-j4" PKGDIR="/common/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="amd64 X aalib acpi alsa audiofile avi berkdb bitmap-fonts bzip2 cdr cli crypt cscope cups curl dri dvd dvdr eds emacs emboss encode esd exif expat f77 fam firefox font-server foomaticdb fortran gdbm gif glut gnome gpm gstreamer gtk gtk2 gtkhtml hal imagemagick imlib ipv6 isdnlog jpeg lcms libcaca logrotate lzw lzw-tiff mng motif mozilla mp3 mpeg ncurses nfs nls nptl nptlonly opengl pam pam_console pcre pdflib perl png ppds pppd python qt quicktime readline recode reflection ruby sdl session spell spl ssl tcltk tcpd tiff truetype truetype-fonts type1-fonts udev usb vim-with-x xinerama xml2 xmms xorg xpm xv xvid zlib userland_GNU kernel_linux elibc_glibc" Unset: ASFLAGS, CTARGET, INSTALL_MASK, LANG, LC_ALL, LDFLAGS, LINGUAS
