xpdf (pdftotext) with language pack call from different directory

Question

I am experimenting with xpdf (pdftotext) on a macOS Terminal. I use one language package (Japanese). Everything works fine if I call the executable like this (from the lib directory):

lib kelly$ ./p2t -enc UTF-8 jp.pdf 

and my data structure

files/lib/pdftotext
files/lib/xpdfrc
files/lib/jp.pdf #file to convert
files/options/Enc/jp/ # Here I have the language package files

and the following edited xpdfrc configuration file:

#----- begin Japanese support package (2011-sep-02)
cidToUnicode    Adobe-Japan1    ../options/Enc/jp/Adobe-Japan1.cidToUnicode
unicodeMap  ISO-2022-JP ../options/Enc/jp/ISO-2022-JP.unicodeMap
unicodeMap  EUC-JP      ../options/Enc/jp/EUC-JP.unicodeMap
unicodeMap  Shift-JIS   ../options/Enc/jp/Shift-JIS.unicodeMap
cMapDir     Adobe-Japan1    ../options/Enc/jp/CMap
toUnicodeDir            ../options/Enc/jp/CMap
#----- end Japanese support package

the problem I have is to call 'pdftoext' from a different directory, for example from 'files'. In this case, the files that the configuration files is pointing to are not seen.

files kelly$ ./lib/p2t -enc UTF-8 ./lib/jp.pdf 

I get the following error:

Syntax Error: Unknown character collection 'Adobe-Japan1'

And the generated file is garbage.

Any idea on how the configuration file needs to be changed?

I was able to solve a similar problem. I installed pdftotext with a brew cask.

The installation was done with the following command

$ brew cask install pdftotext
$ pdftotext -v
pdftotext version 3.03

and place the xpdfrc/language support packages in the following directory I did.

ls /usr/local/etc/xpdfrc
/usr/local/etc/xpdfrc

I downloaded the Japanese Language Pack from here. https://www.xpdfreader.com/download.html
