py2exe problem with os.path

[Tom]

I have the following program to count lines in python:

'''
count number of lines in source files
'''
import os,sys,fnmatch

total=0
fileinfo=[]

exts=[]
for param in sys.argv:
    if param[:2]=='*.':
        exts.append(param)

subdir=0
for param in sys.argv:
    if param.lower()=='-r':
        subdir=1
        break

def Stat(file):
    lines = open(file).readlines()
    result=len(lines)

    return result

def DirInfo(dirpath='./',subdir=1):
    global total,fileinfo,exts

    files=os.listdir(dirpath)

    files.sort()
    for file in files:
        if os.path.isfile(dirpath+file): # Problem line 35
            for ext in exts:
                if fnmatch.fnmatch(file,ext):
                    size=Stat(dirpath+file)
                    total+=size
                    fileinfo.append((os.path.abspath(dirpath+file),size))
        if subdir and os.path.isdir(dirpath+file):
            DirInfo(dirpath+file+'/')

DirInfo(subdir=subdir)

fileinfo.sort(lambda x,y:cmp(y[1],x[1]))

print '-'*79
for (file,size) in fileinfo:
    print file.ljust(70),str(size).rjust(8)

print '-'*79
print 'TOTAL Lines:'.ljust(70),str(total).rjust(8)

When using py2exe it builds fine but when running exe i get:

What is wrong ?
