...hmm, it's in Manips/vertex_program.cpp, specifically:

void vertex_program :: openMess(t_symbol *filename)
{
   char buf2[MAXPDSTRING];
   char *bufptr=NULL;

   if(NULL==filename || NULL==filename->s_name || &s_==filename ||  
0==*filename->s_name)return;

   // Clean up any open files
   closeMess();

   int fd=-1;
   if ((fd=open_via_path(canvas_getdir(getCanvas())->s_name, filename- 
 >s_name, "",
                         buf2, &bufptr, MAXPDSTRING, 1))>=0){
     close(fd);
     sprintf(m_buf, "%s/%s", buf2, bufptr);
   } else
     canvas_makefilename(getCanvas(), filename->s_name, m_buf,  
MAXPDSTRING);

   FILE *file = fopen(m_buf,"r");
   if(file) {
     fseek(file,0,SEEK_END);
     int size = ftell(file);
     m_programString = new char[size + 1];
     memset(m_programString,0,size + 1);
     fseek(file,0,SEEK_SET);
     fread(m_programString,1,size,file);
     fclose(file);
   } else {
     m_programString = new char[strlen(m_buf) + 1];
     strcpy(m_programString,m_buf);
   }
   m_size=strlen(m_programString);
   m_programType=queryProgramtype(m_programString);
   if(m_programType==GEM_PROGRAM_none){
     m_programID = 0;
     char *s = m_programString;
     while(*s && *s != '\n') s++;
     *s = '\0';
     post("[%s]: unknown program header \"%s\" or error open \"%s\"  
file\n",
	 m_objectname->s_name,
	 m_programString,filename->s_name);

     delete m_programString; m_programString=NULL;
     m_size=0;
     return;
   }

   post("[%s]: Loaded file: %s\n", m_objectname->s_name, m_buf);
}

...I think the part to focus on here would be "open_via_path()"...

...the only fonts that are distributed with Gem are the ones in the  
examples/data folder, and the help files are setup to reference them  
there...but it makes more sense to have the normal pd paths looked in  
when search for a font:  perhaps we should add the system fonts to  
(ie. /Library/Fonts, /System/Library/Fonts, ~/Library/Fonts )?
