Recently, after pkg-get upgrade on Solaris 5.10. I encountered a missing file error:

libintl.so.8: open failed: No such file or directory

Reinstalling libintl8 fix the problem. Go to ibiblio.org repository and download the latest version:

# /bin/wget -c http://mirrors.ibiblio.org/pub/mirrors/opencsw/current/sparc/5.10/libintl2-0.18.1.1,p,REV=2011.02.12-SunOS5.9-sparc-CSW.pkg.gz

Install the package:

# gunzip libintl2-0.18.1.1,p,REV=2011.02.12-SunOS5.9-sparc-CSW.pkg.gz
# pkgadd -d libintl8-0.18.1.1,p,REV=2011.03.15-SunOS5.9-sparc-CSW.pkg
