First of all format both the files like this.

Code:
sed 's/^  *//g' file1 | xargs -d"|" -n2 | sort > formattedFile1
sed 's/^  *//g' file2 | xargs -d"|" -n2 | sort > formattedFile2

This will show following output.

Code:
formattedFile1
SUNWzlib  The Zip compression library|(sparc) 11.10.0,REV=2005.01.08.05.16
SUNWzoner  Solaris Zones (Root)|(sparc) 11.10.0,REV=2005.01.21.15.53
SUNWzoneu  Solaris Zones (Usr)|(sparc) 11.10.0,REV=2005.01.21.15.53
SUNWjfca  JNI Fibre Channel Adapter (FCA) Driver|(sparc) 11.10.0,REV=2005.01.04.02.17

formattedFile2
SUNWzoner  Solaris Zones (Root)|(sparc) 11.10.0,REV=2005.01.21.15.53
SUNWzlib  The Zip compression library|(sparc) 12.10.0,REV=2005.01.08.05.16
SUNWzoneu  Solaris Zones (Usr)|(sparc) 11.10.0,REV=2005.01.21.15.53

Now u can simply compare 2 files using grep command.

Code:
grep -x -v -f formattedFile1 formattedFile2          # Lines exists only in File2
grep -x -v -f formattedFile2 formattedFile1          # Lines exists only in File1

zgrep

ZGREP(1)                                                      General Commands Manual                                                     ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
