[yt-users] yt installation script fails with the message "usr/bin/ld: cannot find -lgcc_s".

[Prasanth]

Hello,

The yt installation script fails with the message "usr/bin/ld: cannot find
-lgcc_s" . I am running Ubuntu 11.04. The script is the one at
http://hg.yt-project.org/yt/raw/stable/doc/install_script.sh, and I ran it
a few hours ago.

The full yt_install.log is very large and I can't upload it to pastebin.com.
Let me know if these is a way of sharing it. I am including a few lines
from the beginning and the end of yt_install.log.

The first few lines from yt_install.log:

If compilation produces errors, or a large number of warnings,
please read README.COMPILATION.PROBLEMS -- you might be able to
adjust the flags in this Makefile to improve matters.

Also in README.COMPILATION.PROBLEMS are some hints that may help
if your build produces an executable which is unable to correctly
handle so-called 'large files' -- files of size 2GB or more.

Last few lines from yt_install.log:
