According to enscript man
the installation path for enscript should as follows:
FILES
/usr/share/enscript/*.hdr header files
/usr/share/enscript/*.enc input encoding vectors
/usr/share/enscript/enscript.pro PostScript prolog
/usr/share/enscript/*.afm AFM files for PostScript fonts
/usr/share/enscript/font.map index for the AFM files
/usr/share/enscript/enscript.st states definition file
/usr/etc/enscript.cfg system-wide configuration file
/usr/etc/enscriptsite.cfg site configuration file
~/.enscriptrc personal configuration file
~/.enscript/ personal resource directory
The output of the command find in your case was as follows:
enscript-1.6.6$ find . -name enscript.pro
./share/enscript/enscript.pro
The command above indicates that you ran the command find inside the enscript folder. Usually the output should be:
./enscript.pro
I would suggest that you do:
cd /usr/share/enscript
Then run the command
ll
