if returns "unknown test operator"
Greetings, using ksh on Solaris, I am trying to identify the current version of a package installed on multiple servers using if statement in a precursor to upgrading.
I have searched the forums and have found many hits, reviewed 3 pages and have tried the different variations noted there. Also checked the site, Bourne/Korn Shell Coding Conventions at OpenSolaris.org to validate operators and syntax, yet I am not getting this to work.
I have tried the following variations and all return some error, most commonly:

ksh: 1.11: unknown test operator
no

Am I missing something simple?

Code:
if [ echo "`pkginfo -x \`pkginfo | grep libiconv | awk '{print $2}'\` | grep sparc | awk '{print $2}'`" = 1.11 ]
then
echo yes
else
echo no
fi
 
if [ echo "`pkginfo -x \`pkginfo | grep libiconv | awk '{print $2}'\` | grep sparc | awk '{print $2}'`" eq 1.11 ]
then
echo yes
else
echo no
fi
 
if [ echo "`pkginfo -x \`pkginfo | grep libiconv | awk '{print $2}'\` | grep sparc | awk '{print $2}'`" eq "1.11" ]
then
echo yes
else
echo no
fi
 
if [ echo "`pkginfo -x \`pkginfo | grep libiconv | awk '{print $2}'\` | grep sparc | awk '{print $2}'`" -eq "1.11" ]
then
echo yes
else
echo no
fi
 
if [[ echo "`pkginfo -x \`pkginfo | grep libiconv | awk '{print $2}'\` | grep sparc | awk '{print $2}'`" -eq "1.11" ]]
then
echo yes
else
echo no
fi
 
if [ echo "\"`pkginfo -x \`pkginfo | grep libiconv | awk '{print $2}'\` | grep sparc | awk '{print $2}'`\"" -eq "1.11" ]
then
echo yes
else
echo no
fi

grep

GREP(1) 						      General Commands Manual							   GREP(1)

NAME

       grep - search a file for lines containing a given pattern

SYNOPSIS

       grep [-elnsv] pattern [file] ...

OPTIONS

       -e     -e pattern is the same as pattern

       -c     Print a count of lines matched

       -i     Ignore case

       -l     Print file names, no lines

       -n     Print line numbers

       -s     Status only, no printed output

       -v     Select lines that do not match

EXAMPLES

       grep mouse file	   # Find lines in file containing mouse

       grep [0-9] file	   # Print lines containing a digit

DESCRIPTION

       Grep  searches  one  or	more  files (by default, stdin) and selects out all the lines that match the pattern.  All the regular expressions
       accepted by ed and mined are allowed.  In addition, + can be used instead of * to mean 1 or more occurrences, ? can be used to mean 0 or  1
       occurrences,  and  |  can  be used between two regular expressions to mean either one of them.  Parentheses can be used for grouping.  If a
       match is found, exit status 0 is returned.  If no match is found, exit status 1 is returned.  If an error is detected,  exit  status  2	is
       returned.
