compressing the man pages wouldn't have helped? well, they 
are available online. eh.

What I used to do was generate the makefile again from the 
source tarball. Do the whole tar blah cd blah and then read 
through the LFS book to see how it was configured. This does 
assume that the package was initially configured according 
to the book. Hopefully you can recreate any differences 
between your particular setup and the LFS instructions. 
Anyway, once the makefile was generated, just run make 
uninstall. Most packages support this. Then, be sure to note 
any dependencies listed in the LFS book and try to reinstall 
them without the now non-existent package. This may be a 
pain, but may also be worth it. It won't work with every 
package, but most.

While we're on the subject, I just want to say that I wish 
the install-log package was mentioned explicitly in the 
essential prereading text. This package has been a really 
really nice comfort. It is very useful when removing 
packages installed from source.
