Bugzilla Bug 50176

EMBOSS programs using the plplot library (such as prettyplot and dottup)
terminate with an error message (see below) when trying to produce X11 graphs.
This is due to a misconfiguration of the PLPLOT_LIB environment variable, which
sould be set to "/usr/share/EMBOSS" (this is where the font files are) rather
than "/usr/share/EMBOSS/plplot/lib", (which does not even exist). This change
should go in Portage file : app-sci/emboss/files/22emboss, which is copied to
/etc/env.d/ during EMBOSS installation.

Reproducible: Always
Steps to Reproduce:
$ prettyplot asis::ACTGACTGCTAGCATCGACAT
Actual Results:  
Program aborted (see error message below) 

Expected Results:  
Find the font files in /usr/share/EMBOSS and draw the X11 graph. 

Error message from prettyplot output : 

PLPLOT_LIB="/usr/share/EMBOSS/plplot/lib" 

Cannot open library file: plstnd5.fnt 

Please set PLPLOT_LIB to the plplot/lib directory under emboss 

*** PLPLOT ERROR *** 
Unable to open font file 
Program aborted

Thanks for the hint. Fixed in -r2
