pdf2txt directory path?

I'm having trouble getting the module to accept my Pdf2txt directory path.

My bin files are here:

/home/myacct/.local/bin

so that directory includes things like

dumppdf.py
dumppdf.pyc
latin2ascii.py
latin2ascii.pyc
pdf2text
pdf2txt.py
pdf2txt.pyc
pip

My lib files are here:

/home/myacct/.local/lib/python2.7/site-packages

so that directory includes subdirectories like

pdf2text
pdf2text-1.0.0.dist-info
pdfminer
pdfminer-20140328.dist-info
pip

I also see that some files are named pdf2txt and others are pdf2text.

No matter what I try to put in my "Pdf2txt directory path" field, I get

"Pdf2txt Python script not found at this path."

I've tried

/home/myacct/.local/bin
/home/myacct/.local/lib/python2.7/site-packages
/home/myacct/.local/lib/python2.7/site-packages/pdf2text

Can you clarify what I should put in the directory path and script file fields? I've tried following the help text, but it's not working for me.

Thanks!
