[gentoo-user] trouble installing help2man on new gentoo box

[gentoo-user] trouble installing help2man on new gentoo box

[Allan Gottlieb]

I am reinstalling gentoo on a Dell inspiron 6400 laptop
I am (again) using lvm2.

I just built the kernel and then (following the lvm2 guide) tried

emerge lvm2

This required a build of help2man, which failed with

Any help would be appreciated.

I thought that instead of mounting /dev/vg/usr on /usr
I would mount it at /mnt/usr and have /usr a symlink to /mnt/usr

(Similarly for opt et al)

This worked for a while but
/usr/lib/libdl.so is a symlink to ../../lib64/libdl.so.2
and the symlink uses physical not logical interpretation of ..

Hence /usr/lib/../..  is /mnt instead of /

oops.

I was thinking of reading the details of bind mounting, but decided I
spent/wasted enough time trying to have a "clean" system with all
mounting at /mnt.  If your suggestion meant that usr would be mounted at
both / and /mnt, I don't see that as any cleaner than having it just at /.

If the purpose was to "document" all the mounts by having them at /mnt,
I could do that with a symlink

    ln -s /usr /mnt/usr

I still feel it is somehow "cleaner" to have all mount points be
in /mnt, but am cutting my losses.

thanks for the suggestion.
