[Liblas-devel] Problem to import liblas module in Python 2.7

[Alessandro Montaghi]

i have also a liblas working on my home PC (64-bit and Python 2.7). I
copied and pasted the *.dll files from my Home PC to my Work Pc but i get
always the same error.

just some stuff:

*"Python where we can, C++ where we must"*

*Top 10 Things That Computer Programmers Hate:*
     1. Waking Up Early
     2. Writing The F*cking Manual
     3. Not Drinking Coffee
     4. Reviewing Your Own Code 3 Months Later
     5. codes from other programmers without comments
     6. Error Checking
     7. (Not) Backing Up
     8. Debugging
     9. Leaving The House When Important Findings Come Up
    10. Mathematic or Physics Formulas
